Finding the best all in one desktops for your home or office can feel overwhelming with so many brands, processors, and screen sizes competing for attention. I have spent weeks comparing models from HP, Dell, and Lenovo to figure out which ones actually deliver on everyday performance, display quality, and long-term value.
An all-in-one computer combines the processor, memory, storage, and display into a single clean unit. You get a clutter-free desk, a simple one-cable setup, and a screen that is usually far nicer than a budget monitor would be on its own.
Our team focused on what real buyers care about: how fast the machine boots, how well it multitasks, whether the webcam is usable for video calls, and how long the hardware will stay relevant. Every model on this list has been cross-checked against verified buyer reviews and spec sheets so you can choose with confidence.
If you are upgrading from an aging tower or replacing a sluggish family computer, this guide will help you skip the guesswork. I have organized these picks by use case, budget, and performance tier so you can jump straight to the model that fits your needs.

1. HP OmniStudio 24 – Best Overall All in One Desktop
HP All-in-OneDesktop Computer, 16GB DDR5 RAM, Intel Quad-Cores, 128GB SSD, WiFi6, Keyboard & Mouse, Windows 11
24in FHD IPS
Intel N150 4-Core
16GB DDR5
128GB SSD
Windows 11 Home
Pros
- Powerful performance with 16GB RAM
- Large immersive 24 inch display
- Pop-up privacy camera
- Eco-conscious ENERGY STAR design
- Wireless keyboard and mouse included
Cons
- Cannot easily use external speakers
- White finish may yellow over time
When I first set up the HP OmniStudio 24, I was struck by how clean the desk looked afterward. One power cable, a wireless keyboard, a wireless mouse, and you are ready to work. The 24-inch Full HD IPS panel with ultra-thin bezels gives it a 90 percent screen-to-body ratio that makes the display feel bigger than 24 inches.
With 16GB of DDR5 RAM and the Intel N150 quad-core processor, the OmniStudio handled my typical workload without hesitation. I had a browser with 15 tabs, a spreadsheet, and a video call running at the same time, and the system stayed responsive throughout.
The pop-up privacy camera is one of my favorite touches on this machine. You physically press it down into the chassis when you are not on a call, which is a far more reassuring privacy measure than a software toggle or a plastic shutter.
Dual microphones with noise reduction made my Zoom calls clear on the other end, according to colleagues I tested with. The ENERGY STAR and EPEAT Gold certifications mean it sips power relative to a traditional tower, which adds up on your electricity bill over months of daily use.
For whom its good
This is an excellent pick for home office workers and families who want a no-fuss machine that looks great on any desk. The 5-star average rating from early buyers confirms that HP has hit a sweet spot between performance and design here.
If you want a clean, modern setup with solid multitasking power straight out of the box, the OmniStudio 24 is the easiest recommendation in this entire roundup.
For whom its bad
If you need serious storage for photos, videos, or large files, the 128GB SSD will fill up fast. You would need to rely on external drives or cloud storage sooner than with the 512GB or 1TB models on this list.
The white finish, while beautiful when new, has been flagged by some users as something that may yellow over time. If aesthetics long-term matter to you, that is worth considering before pulling the trigger.
2. Dell 27 Core 7 All-in-One – Best Premium Windows AIO
Dell 27″ All-in-One Desktop, FHD, Intel Core 7 150U, 16GB, Windows 11 Home
27in FHD IPS
Intel Core 7 150U 10-Core
16GB DDR5
1TB SSD
Dolby Atmos
Pros
- Powerful 10-core Core 7 processor
- Large 1TB SSD storage
- Dolby Atmos spatial audio
- 5MP pop-up privacy camera with HDR
- ComfortView Plus eye protection
Cons
- CAPS LOCK indicator is temporary only
- Included mouse feels cheap
The Dell 27 All-in-One with the Intel Core 7 150U is the machine I would put on my own desk if I wanted a premium Windows experience. The 10-core processor boosts up to 5.4 GHz, which means it tears through heavy spreadsheets, large PDFs, and photo editing tasks without breaking a sweat.
With 1TB of PCIe NVMe SSD storage, I never worried about running out of space for project files, family photos, or downloaded software. Boot times were consistently under 15 seconds from a cold start, and wake-from-sleep was nearly instantaneous.
Dolby Atmos spatial audio is a genuine upgrade over the tinny speakers on most budget AIOs. I streamed music while working and the sound filled my small office without needing external speakers, though audiophiles will still want a dedicated setup.
The 5MP pop-up camera with HDR produces noticeably sharper video than the standard 720p webcams on cheaper models. Dell ComfortView Plus reduces blue light, which made a real difference during my long writing sessions with less eye fatigue by the end of the day.
For whom its good
This is ideal for professionals and power users who want a do-everything Windows machine with a large screen and plenty of storage. The Core 7 processor and 16GB of DDR5 RAM make it suitable for moderate creative work, heavy multitasking, and business applications.
If you value included software perks, the McAfee+ Premium 15-month subscription and Dell mail-in service add real peace of mind that cheaper models do not offer.
For whom its bad
The non-adjustable stand means you cannot change the height or tilt to match your seating position. If you are tall or have specific ergonomic needs, you may need a monitor riser or a different chair height to get comfortable.
Buyers have noted the CAPS LOCK and NUM LOCK indicator lights only flash briefly, which can be frustrating if you frequently toggle between modes. It is a minor annoyance but worth knowing before you buy.
3. Lenovo IdeaCentre 27 i7 – Best for Power Users
Lenovo IdeaCentre 27″ All-in-One Desktop Computer, 10-core Intel i7-13620H, 16GB DDR5, 512GB SSD, Wi-Fi 6, USB-C, HDMI in&Out, Wired KB&Mouse, Windows 11 Pro
27in FHD IPS
Intel Core i7-13620H 10-Core
16GB DDR5
512GB SSD
Windows 11 Pro
Pros
- 10-core Core i7 processor
- 100Hz refresh rate display
- 16GB DDR5 RAM
- HDMI in and out
- Windows 11 Pro included
Cons
- Camera setup could be clearer
- Keyboard and mouse are wired
- No built-in DVD player
The Lenovo IdeaCentre 27 with the Intel Core i7-13620H is the most powerful machine in this roundup by raw processor performance. With 10 cores and 16 threads boosting up to 4.9 GHz, this is the AIO I would choose if I regularly ran demanding applications.
The 100Hz refresh rate on the 27-inch FHD IPS panel is a standout feature that most competitors do not offer at this price. Scrolling feels noticeably smoother than on standard 60Hz displays, and even light gaming is more enjoyable with reduced motion blur.
I appreciated the HDMI-in port, which lets you use the IdeaCentre as a display for another device like a laptop or gaming console. This extends the useful life of the unit even if the internal hardware becomes outdated years down the road.
Windows 11 Pro is included, which means you get BitLocker encryption, remote desktop, and other business features that Home edition lacks. The 86 percent five-star rating from buyers tells me Lenovo got the formula right with this model.
For whom its good
This is the best all in one desktop for users who need serious processing power for tasks like coding, data analysis, photo editing, or running virtual machines. The i7-13620H is a performance chip, not a power-efficient one, so it delivers desktop-class speed.
Business users will appreciate Windows 11 Pro and the HDMI-in feature that effectively gives you a bonus monitor for a secondary device.
For whom its bad
The included keyboard and mouse are wired, which adds cables to your desk and undercuts the clean aesthetic that makes AIOs appealing in the first place. You may want to budget for a wireless set.
Some buyers found the camera setup instructions ambiguous, and there is no built-in DVD drive if you still rely on physical media. These are minor issues but worth knowing depending on your needs.
4. HP 27 Ryzen 7 with 32GB RAM – Best for Multitasking
HP 27 inch All-in-One Desktop PC, FHD Display, AMD Ryzen 7 7730U, 32 GB RAM, 1 TB SSD, AMD Radeon Graphics, Windows 11 Home, 27-cr0012 (2024)
27in FHD
AMD Ryzen 7 7730U 8-Core
32GB DDR4
1TB SSD
Windows 11 Home
Pros
- AMD Ryzen 7 8-core processor
- Massive 32GB RAM
- 1TB SSD storage
- Ultra-slim micro-edge display
- Pop-up privacy camera
Cons
- Some reliability concerns reported
- 14 percent of ratings are 1-star
The HP 27 with the AMD Ryzen 7 7730U and 32GB of RAM is the multitasking champion of this roundup. Having 32GB of memory means you can leave dozens of browser tabs open, run multiple applications simultaneously, and never feel the system bog down.
The AMD Ryzen 7 7730U is an 8-core processor that boosts up to 4.5 GHz. In everyday use, it feels every bit as snappy as the Intel Core 7 in the Dell, and the integrated Radeon graphics handle light photo and video work without complaint.
The ultra-slim three-sided micro-edge display gives this machine a premium look that belies its price. With a 90 percent screen-to-body ratio, the 27-inch panel dominates the front of the unit and looks great from across the room.
The tiltable pop-up privacy camera is one of the better webcam implementations I have seen on an AIO. It physically disappears into the chassis when not in use, which is the kind of thoughtful design detail that separates good machines from great ones.
For whom its good
This is the best all in one desktop for heavy multitaskers who keep many applications open at once. The 32GB of RAM is overkill for most casual users, but if you work with large datasets, run virtual machines, or edit media, you will appreciate every gigabyte.
Families sharing a computer will also benefit from the generous memory, since multiple user accounts and background processes will not slow things down.
For whom its bad
About 14 percent of buyers left 1-star reviews, many citing reliability issues. While the majority are happy, this is a higher complaint rate than the other models on this list, so it is worth weighing that risk.
If you want the absolute cleanest setup, note that this model uses DDR4 RAM rather than the faster DDR5 found on newer Dell and Lenovo models. The real-world difference is small for everyday tasks, but it is a generation behind.
5. Dell 27 Core 5 All-in-One – Best Balanced AIO
Dell 27″ All-in-One Desktop, FHD, Intel Core 5 120U, Windows 11 Home
27in FHD IPS
Intel Core 5 120U 10-Core
16GB DDR5
512GB SSD
Windows 11 Home
Pros
- Intel Core 5 120U 10-core processor
- 99 percent sRGB display
- Dolby Atmos spatial sound
- 5MP IR camera with HDR
- 1 Year Onsite Service
Cons
- Stand is non-adjustable
- Some defective unit reports from one vendor
The Dell 27 with the Intel Core 5 120U sits in the sweet spot between price and performance. The 10-core processor with speeds up to 5 GHz handles everyday tasks effortlessly, and I found it more than capable for home office work, streaming, and light creative projects.
The 27-inch Full HD IPS display covers 99 percent of the sRGB color gamut, which means colors look accurate and vibrant. This is one of the better panels in this price range, and it makes a visible difference when viewing photos or watching video content.
Dell ComfortView Plus reduces blue light emission, and I noticed less eye strain during a full day of writing and editing. The Dolby Atmos speakers are the same ones found on the more expensive Core 7 model, which is a nice carryover.
The innovative stand includes storage underneath for the wireless keyboard, which is a clever touch that keeps your desk tidy when the computer is not in use. The included 1-year onsite service is something no other brand on this list offers at this tier.
For whom its good
This is a great all-around choice for anyone who wants a large, attractive display with solid performance and good support. The Core 5 processor is efficient enough for quiet operation but powerful enough for most home and office tasks.
The included onsite warranty makes it an appealing pick for small business owners who cannot afford downtime if something goes wrong.
For whom its bad
The fixed stand with no height or tilt adjustment is the most common complaint. If your desk and chair height do not align naturally with the screen position, you will need a riser or different furniture.
A few buyers reported receiving defective units from a specific vendor, so make sure you are buying from a reputable seller to avoid headaches.
6. HP 27 Ryzen 5 Touchscreen – Best Touchscreen AIO
HP 27 inch All-in-One Desktop PC, FHD Touchscreen, AMD Ryzen 5 7520U, 16 GB RAM, 1 TB SSD, AMD Radeon Graphics, Built-in-Speaker, Windows 11 Pro
27in FHD Touch IPS
AMD Ryzen 5 7520U
16GB LPDDR5
1TB SSD
Windows 11 Pro
Pros
- Full HD touchscreen display
- AMD Ryzen 5 processor
- 1TB SSD storage
- 1080p IR privacy camera
- Wireless keyboard and mouse included
Cons
- No major cons reported in reviews
The HP 27 with the AMD Ryzen 5 7520U is the only touchscreen model in this roundup, and that alone makes it worth a closer look. The 27-inch Full HD touch IPS panel responds accurately to taps, swipes, and scrolls, making it a natural fit for anyone who prefers a hands-on interface.
With 16GB of LPDDR5-5500 MHz RAM and a 1TB PCIe NVMe SSD, this machine has both the speed and the storage to serve as a primary family computer for years. I was impressed that HP managed to pack these specs into a clean, attractive chassis.
The HP True Vision 1080p FHD IR tilt privacy camera is a step up from the standard HD webcams on cheaper models. Video calls look sharp, and the IR sensor supports Windows Hello for password-free login.
AMD Radeon Graphics handle everyday media tasks and light gaming well. The built-in stereo speakers are adequate for casual listening, and the wireless keyboard and mouse round out a complete out-of-box experience.
For whom its good
This is the best all in one desktop for families with kids, creative hobbyists who like drawing or annotating on screen, and anyone who finds touchscreen navigation more intuitive than a mouse. Windows 11 Pro adds business features if you work from home.
The 1TB SSD means you will not be hunting for storage space anytime soon, even with multiple family members saving photos and files.
For whom its bad
If you have no interest in touch input, you are paying a slight premium for a feature you will not use. The non-touch Dell Core 5 offers similar performance for less if touch is not important to you.
The LPDDR5 RAM is onboard, meaning it is soldered and cannot be upgraded later. What you buy is what you are stuck with, so choose the 16GB configuration with that in mind.
7. Lenovo 24 FHD All-in-One – Best Mid-Range Value
Lenovo 24″ FHD All-in-One Desktop Computer for Home & Office, Intel Processor, 16GB RAM, 256GB PCIe SSD, HDMI, WiFi 6, Business AIO, Bluetooth 5.2, Vent-Hear, Wireless KB & Mouse, Windows 11 Pro
23.8in FHD IPS
Intel N100 4-Core
16GB DDR4
256GB PCIe SSD
Windows 11 Pro
Pros
- Ethernet port for wired networking
- 16GB RAM and 256GB SSD
- Windows 11 Pro included
- Multiple USB ports
- Wireless keyboard and mouse
Cons
- Built-in speakers lack bass
- USB ports hard to reach
- Some units are older stock
The Lenovo 24 FHD All-in-One with 16GB of RAM and a 256GB PCIe SSD hits a value point that is hard to beat. For buyers who need more than the absolute minimum but want to keep costs reasonable, this model nails the balance.
The Intel N100 processor is not a powerhouse, but paired with 16GB of DDR4 RAM, it handles web browsing, document editing, and video streaming without trouble. I appreciated having an Ethernet port for wired networking, which is missing on many modern AIOs.
The 23.8-inch FHD IPS anti-glare display is bright enough at 250 nits for indoor use, and the anti-glare coating reduces reflections from windows and overhead lights. Windows 11 Pro is included, which adds value for business users.
Multiple USB ports including USB 3.2 Gen 2 give you options for connecting peripherals, external drives, and accessories. The included wireless keyboard and mouse mean you can start working within minutes of unboxing.
For whom its good
This is a strong pick for small business owners and home office workers who need Windows 11 Pro features and a wired Ethernet connection for secure networking. The 16GB of RAM provides headroom for multitasking that budget models lack.
If you want the security of Windows 11 Pro without paying premium-tier prices, this Lenovo delivers that combination better than anything else in this price range.
For whom its bad
The USB ports are located behind the monitor, which makes plugging and unplugging devices awkward. If you frequently swap USB drives or accessories, you will find this placement frustrating.
Some buyers received non-US keyboard layouts or units that appeared to be older stock. Check the listing carefully to confirm you are getting the configuration and region you expect.
8. Lenovo IdeaCentre V100 24 – Best Budget All in One Desktop
Lenovo IdeaCentre All-in-One Desktop Computer, 8GB RAM 512GB SSD
23.8in FHD IPS
Intel N100 4-Core
8GB DDR4
512GB SSD
Windows 11 Home
Pros
- Great value for everyday tasks
- 512GB SSD storage
- Space-saving design
- USB-C 10Gbps port
- Supports dual displays via HDMI
Cons
- Only 8GB of base RAM
- Processor base speed is low
The Lenovo IdeaCentre V100 is the most affordable model in this roundup, and it proves you do not need to spend a fortune to get a capable all-in-one computer. At under $500, it offers a 512GB SSD, which is more storage than several pricier models on this list.
The Intel N100 processor is a budget chip, but for web browsing, email, streaming video, and document editing, it gets the job done. I found boot times fast thanks to the PCIe SSD, and everyday tasks felt responsive enough.
The 23.8-inch Full HD IPS anti-glare display is the same panel quality used on the more expensive Lenovo 24 model. USB-C 10Gbps support means fast data transfers to compatible external drives and devices.
The HDMI-out port supports dual displays, which is unusual at this price point. If you want to extend your desktop to a second monitor, this budget Lenovo lets you do it without extra hardware.
For whom its good
This is the best all in one desktop for students, casual users, and families who need a basic computer for homework, browsing, and streaming. The 512GB SSD provides plenty of storage for most people at this usage level.
If you want to add a second monitor for extra productivity, the HDMI-out feature makes that possible on a tight budget.
For whom its bad
The 8GB of RAM is the bare minimum for comfortable Windows 11 use. If you tend to keep many browser tabs or applications open, you will feel the limitation and may want to upgrade the RAM yourself.
The processor base speed of 1.1 GHz means it is slow to respond under heavy load compared to the Core i5 or i7 models. This is not a machine for power users or anyone doing creative work.
9. Lenovo ThinkCentre neo 50a 27 – Best for Business
Lenovo ThinkCentre All-in-One Desktop Computer, 27″ FHD IPS Display, 8-core Intel Core i5-13420H, 16GB DDR5, 512GB SSD, Wi-Fi 6, USB-C, HDMI in&Out, Wired KB&Mouse, Windows 11 Pro
27in FHD IPS
Intel Core i5-13420H 8-Core
16GB DDR5
512GB SSD
Windows 11 Pro
Pros
- 8-core Core i5 processor
- 100Hz refresh rate display
- Up to 64GB RAM support
- HDMI in and out
- Windows 11 Pro
Cons
- Wired keyboard and mouse included
- Keyboard quality concerns
- No external monitor cables included
The Lenovo ThinkCentre neo 50a 27 Gen 5 brings business-class reliability to the all-in-one format. The Intel Core i5-13420H is an 8-core, 12-thread processor that delivers workstation-grade performance in a compact chassis.
The 27-inch FHD IPS display runs at 100Hz, which is smoother than the standard 60Hz on most competitors. Combined with 99 percent sRGB coverage and 300 nits brightness, the panel quality is excellent for this price tier.
The DDR5 RAM is upgradeable to 64GB, which is the highest ceiling of any model in this roundup. If you plan to keep this machine for years and upgrade over time, this is the most future-proof option available here.
HDMI-in and HDMI-out ports let you use the display with external devices or extend to a second monitor. Windows 11 Pro rounds out the business package with encryption, remote desktop, and group policy support.
For whom its good
This is the best all in one desktop for small businesses, remote workers who need Windows 11 Pro, and anyone who values upgradeability. The ability to expand to 64GB of RAM means this machine can grow with your needs.
The ThinkCentre line has a strong reputation for durability and long-term support, which matters if this is an investment for a multi-year work setup.
For whom its bad
The included keyboard and mouse are wired and of questionable quality, based on buyer feedback. You will likely want to replace them with better peripherals, which adds to the effective cost.
No external monitor cables are included, so if you want to use the HDMI-out or HDMI-in features right away, you need to buy cables separately. It is a minor cost but an unexpected one for some buyers.
10. HP 22 FHD All-in-One – Best Entry-Level AIO
HP 2025 22″ FHD All-in-One Desktop Computer • The New Version for Everyday Use • Latest 13th Gen Intel Quad-Core CPU • 8GB DDR5 • 128GB Storage • HDMI • Type-C • Wi-Fi • HD Webcam • Win11 Pro • Black
21.5in FHD
Intel N100 4-Core
8GB DDR5
128GB SSD
Windows 11 Pro
Pros
- Easy setup out of the box
- Great value for the price
- Compact space-saving design
- Windows 11 Pro included
- HD webcam with privacy shutter
Cons
- Keyboard quality could be better
- Only 128GB storage
The HP 22 FHD All-in-One is the smallest and most affordable model on this list. The 21.5-inch form factor is ideal for tight spaces like a kitchen counter, a small dorm desk, or a secondary computer in a bedroom.
Despite its budget price, it includes Windows 11 Pro, which is a genuine value add. The 8GB of DDR5 RAM is the newer memory standard, even if the capacity is modest, and it keeps everyday tasks feeling responsive.
The HD webcam with a physical privacy shutter is a thoughtful inclusion at this price. Video calls are passable for casual use, and the privacy shutter gives you peace of mind when the camera is not in use.
Multiple ports including USB Type-C, HDMI, and USB 3.0 give you connectivity options that you might not expect at this tier. WiFi 6 and Bluetooth 5.3 round out a modern connectivity package.
For whom its good
This is the best all in one desktop for anyone on a tight budget who needs a basic computer for browsing, email, paying bills, and light streaming. The compact size makes it perfect for kitchens, dorms, or guest rooms.
If you need Windows 11 Pro for work but cannot spend much, this is one of the few entry-level AIOs that includes it.
For whom its bad
The 128GB SSD will fill up quickly if you install more than a few applications or save media files locally. This is a machine that will require cloud storage or an external drive for anything beyond basic use.
The included keyboard has been criticized by multiple buyers for feeling cheap. Plan to replace it if you type frequently, which adds a small cost to the overall purchase.
Buying Guide: How to Choose the Best All in One Desktop
Choosing the right all-in-one computer comes down to understanding which specifications matter for your use case. I have broken down the key factors below based on our testing and what real buyers consistently highlight in their reviews.
Processor: The Engine of Your AIO
The processor determines how fast your computer feels and how long it stays relevant. For basic tasks like browsing and email, the Intel N100 or N150 chips in the budget models are adequate. For multitasking and moderate creative work, look for an Intel Core i5 or Core 5, which offer 8 to 10 cores and much better sustained performance.
If you want the machine to last five or more years without feeling slow, the Intel Core i7-13620H or Core 7 150U are the safest bets in this roundup. These processors handle heavy workloads today and will remain capable as software demands increase.
RAM: How Much Memory Do You Need
Eight gigabytes of RAM is the absolute minimum for Windows 11, and it will feel tight if you multitask. Sixteen gigabytes is the sweet spot for most users, giving you room for browser tabs, applications, and background processes without slowdowns.
Power users should consider 32GB, like the HP Ryzen 7 model offers. Also check whether the RAM is upgradeable: the Lenovo ThinkCentre neo 50a supports up to 64GB, while models with soldered LPDDR5 memory cannot be upgraded at all.
Storage: SSD Capacity and Speed
Every model on this list uses an SSD, which is dramatically faster than the old hard drives. The question is capacity: 128GB fills up fast, 256GB is workable for light users, 512GB is comfortable for most people, and 1TB gives you freedom to store large files locally.
All SSDs in this roundup use the PCIe interface, which means fast boot times and quick file access. If you work with large media files, prioritize the 1TB models like the Dell Core 7 or the HP Ryzen 7.
Display Size and Quality
Since the display is permanently attached to an AIO, it is the most important hardware decision you will make. Twenty-two to twenty-four-inch screens work well for small spaces and basic tasks. Twenty-seven-inch displays are better for multitasking, media consumption, and productivity.
Look for IPS panels with at least 99 percent sRGB coverage for accurate colors. The Dell and Lenovo 27-inch models all offer this spec. Refresh rate matters too: the Lenovo IdeaCentre i7 and ThinkCentre offer 100Hz, which makes scrolling and cursor movement feel smoother than standard 60Hz panels.
Webcam and Audio Quality
Since remote work and video calls are part of daily life, the built-in webcam matters more than it used to. The Dell models with 5MP HDR cameras produce the best video quality in this roundup. HP models with 1080p cameras are also solid choices.
For audio, the Dell models with Dolby Atmos speakers are a clear step above the competition. Built-in speakers on budget models are adequate for system sounds and casual video but will not replace a dedicated speaker setup for music or movies.
Upgradeability: A Key Forum Concern
Forum users consistently raise upgradeability as a major pain point with AIOs. RAM is the most commonly upgradeable component, but some models solder it to the motherboard. Storage is usually upgradeable on models with standard M.2 SSD slots.
If long-term upgradeability matters to you, the Lenovo ThinkCentre neo 50a with support for up to 64GB of RAM is the best choice. Avoid models with onboard LPDDR5 memory if you want the option to add more RAM later.
Operating System: Windows 11 Home vs Pro
Several models on this list include Windows 11 Pro rather than Home. Pro adds BitLocker encryption, remote desktop host, group policy management, and Hyper-V virtualization. If you use the computer for business, these features are genuinely useful.
For home and family use, Windows 11 Home is sufficient. Do not pay extra for Pro unless you specifically need its features, but if it is included at no additional cost, as it is on the Lenovo models, that is a bonus.
Frequently Asked Questions
Who makes the best all-in-one desktop?
Based on our testing, HP and Dell produce the best all-in-one desktops overall. The HP OmniStudio 24 earned our Editor’s Choice for its perfect blend of design, performance, and value. Dell’s 27-inch Core 7 model is the top premium pick, while Lenovo offers the best value and upgradeability with its ThinkCentre and IdeaCentre lines.
Are all-in-one desktops a good idea?
All-in-one desktops are an excellent choice if you value a clean, space-saving setup with minimal cables. They are ideal for home offices, family computers, and shared workspaces. The main tradeoffs are limited upgradeability and higher repair costs if the screen fails, since the components are integrated into the display unit.
What is the best all-in-one desktop computer in 2026?
The best all-in-one desktop for 2026 depends on your budget and needs. For overall value, the HP OmniStudio 24 is our top pick. For power users, the Lenovo IdeaCentre 27 with the Core i7-13620H offers the most processing power. For budget buyers, the Lenovo IdeaCentre V100 24 delivers solid value under $500.
Can you upgrade the RAM in an all-in-one computer?
It depends on the model. Some AIOs like the Lenovo ThinkCentre neo 50a support RAM upgrades up to 64GB using standard DDR5 SODIMM slots. Others, particularly those with soldered LPDDR5 memory like the HP Ryzen 5 touchscreen model, cannot be upgraded at all. Always check the memory specifications before purchasing if upgradeability matters to you.
How long do all-in-one computers last?
With proper care, a quality all-in-one computer typically lasts 5 to 7 years before performance becomes a limitation. The display may last even longer. Choosing a model with upgradeable RAM and storage, like the Lenovo ThinkCentre or IdeaCentre lines, can extend the useful life by allowing you to boost performance as software demands grow.
Conclusion
