8 Best All in One Computers (September 2026) Tested and Ranked

I spent six weeks putting eight of the best all in one computers through their paces at my home office, and one thing became clear fast. The all-in-one category has changed. What used to be underpowered family PCs now includes AI-ready chips, 100Hz displays, and docking stations in the box.

An all-in-one desktop squeezes the computer, monitor, speakers, and webcam into a single panel. The result is fewer cables, a smaller desk footprint, and a cleaner workspace. That trade-off is great for most people but comes with limits on upgrades and repairs.

Our team compared these models side by side, running daily office apps, photo editing, video calls, and streaming. We judged each on display quality, performance, ports, value, and long-term reliability based on real customer feedback. Below you’ll find our ranked picks, full reviews, a buying guide, and answers to the questions shoppers ask most about AIO computers.

Top 3 Picks for Best All-in-One Computers

Best All-in-One Computers in 2026: Quick Overview

1. HP OmniStudio 27 inch All-in-One Desktop — Editor’s Choice

The OmniStudio is the first AIO that made me want to clear my desk and start fresh. The 27-inch IPS panel has thin bezels, an adjustable stand, and a textured jet-black finish that looks more like furniture than a computer.

I ran this system for two weeks as my daily driver. The AMD Ryzen AI 7 445 handled 20+ Chrome tabs, Slack, Spotify, and a Photoshop session without a hiccup. The 16GB of DDR5 RAM and 512GB SSD kept boot times under 10 seconds.

What surprised me most was the AI feature set. The FHD IR camera auto-switches HDR based on lighting, and Windows Hello logged me in the moment I sat down. AI noise reduction cleaned up my calls enough that coworkers asked if I had a new microphone.

The display hits a clear sweet spot at 100% sRGB with 300 nits. It’s not a creator panel, but for everyday work and streaming, colors look accurate and text stays sharp. DTS Sound gets loud enough to fill a small office.

For ports, you get USB-C 10Gbps, USB-A 10Gbps, USB 2.0, and HDMI-out. Only one USB-C is a letdown, especially on a 2026 AI PC. The fan can spin up under heavy load, but it’s not loud enough to be distracting.

Who this is good for

Anyone who wants a clean, modern Windows AIO with smart AI features for daily work. Great for home offices, students, and remote workers who value simplicity.

If you make a lot of video calls, the Windows Hello camera and noise reduction alone justify the price over older AIO designs.

Who this is bad for

Power users who need to upgrade RAM or storage down the line. The 16GB ceiling is fixed, and the SSD is not user-replaceable.

Shoppers who want a touchscreen or 4K display. This model is FHD only and non-touch.

2. Lenovo IdeaCentre 27 inch i7-13620H — Best Windows Performance

This IdeaCentre is the fastest all-in-one I tested. The 13th Gen Intel Core i7-13620H is a 10-core chip that runs up to 4.9 GHz, and it shows in everyday use.

Photo edits in Lightroom, multi-track timelines in Premiere, and large Excel sheets all felt snappy. The 16GB of DDR5 RAM is the limiting factor, but the great news is it’s expandable to 64GB through two SO-DIMM slots.

The 27-inch 100Hz IPS display was my favorite for scrolling and mouse work. 100Hz is rare in this category, and once you use it, going back to 60Hz feels sluggish. The 99% sRGB coverage and 300-nit brightness make it solid for content work too.

Port selection is the highlight. You get four USB ports plus HDMI-In and HDMI-Out, which is unusual. The HDMI-In lets you plug in a laptop or game console and use the panel as a display, and HDMI-Out supports a second monitor.

The wired keyboard and mouse are nothing special, and the camera setup in Windows was confusing on first try. Otherwise, this is the most well-rounded AIO for Windows users who want real performance.

Who this is good for

Power users, content creators, and small business owners who want desktop-class CPU performance without a tower.

Anyone who values the rare HDMI-In port for connecting a second device to the screen.

Who this is bad for

Shoppers on a tight budget. The i7 chip and 27-inch 100Hz display put this above entry-level AIOs.

Users who want a touchscreen. The IdeaCentre here is non-touch.

3. Dell Inspiron 24 5420 All-in-One — Best Budget White AIO

The Inspiron 24 5420 has been around for a couple of years, but it remains one of the best values in the AIO category. The white chassis and narrow bezels look more expensive than the price suggests.

Inside, the 13th Gen Intel Core i5-1335U has 10 cores and is plenty fast for office work, browsing, and light photo editing. The 16GB of DDR4 RAM and 1TB SSD are generous for the price, and the RAM is expandable to 32GB.

Dell’s ComfortView Plus reduces blue light without making the screen look yellow, which is a big deal for anyone doing long work sessions. The pop-up FHD camera with tilt keeps things private when not in use, and the 1 Year of Premium Support is included.

The 23.8-inch FHD display is a 60Hz panel. It’s sharp, but the 60Hz refresh feels dated next to the 100Hz Lenovo above. The 5 USB ports and 2 HDMI ports are excellent for a budget AIO, including a memory card reader that the others skip.

My main concern is stock. At the time of writing, only one unit was left, and it’s non-Prime. If you can find it in stock, this is a great value pick.

Who this is good for

Students, families, and home office users who want a reliable Windows AIO with good specs and don’t need 100Hz.

Anyone who values the included Premium Support and white design that fits a bright workspace.

Who this is bad for

Shoppers who need Prime fast shipping. The non-Prime delivery option is a real downside here.

Users who want the latest AI features. The 5420 is a 2023 design that ships with older hardware.

4. Dell 27 inch EC27250 AIO — Best Dell 27-Inch

The Dell EC27250 is a newer take on the 27-inch AIO, and the design is the most thoughtful I tested. The stand doubles as a storage compartment for the included keyboard, which kept my desk noticeably cleaner.

The 27-inch FHD IPS display hits 99% sRGB with what Dell calls 50% higher contrast versus prior generations. Side by side with the 24-inch Inspiron, the colors and depth are clearly better. It’s still FHD though, so text is not as crisp as a 4K panel.

The Intel Core 7 150U is a 10-core chip that hits 5.4 GHz, and it powers through spreadsheets, video calls, and dozens of Chrome tabs. 16GB of DDR5 and a 1TB PCIe NVMe SSD round out a balanced spec sheet.

The 5MP IR camera with HDR is a clear upgrade over typical 1080p webcams. Skin tones look natural in mixed lighting, and Windows Hello login is fast. Dolby Atmos dual speakers sound noticeably better than the competition.

Some downsides to know. The keyboard backlight only lights the Caps Lock indicator, not the keys. The included mouse feels cheap. There’s no fingerprint reader, even though the IR camera is there. None of these are deal-breakers, but they keep this from the top spot.

Who this is good for

Dell fans and business buyers who want a 27-inch Windows AIO with strong speakers, a great camera, and a clean desk aesthetic.

Anyone who makes a lot of video calls and would benefit from the upgraded 5MP HDR webcam.

Who this is bad for

Users who want a backlit keyboard. The included keyboard lacks a backlight beyond the Caps Lock indicator.

Shoppers looking for a touchscreen. The EC27250 is not a touch model.

5. HP 27 inch Touchscreen AIO — Best Touchscreen

If you want a touchscreen AIO at a fair price, this HP is the one to look at. The 27-inch FHD IPS touchscreen is responsive, and tapping to scroll through a long document feels natural.

Performance is fine for everyday work. The AMD Ryzen 5 7520U is an older chip, but combined with 16GB of LPDDR5 RAM and a 1TB SSD, it handles office apps, video calls, and streaming without slowing down. Just don’t expect it to keep up with the Ryzen AI 7 in the OmniStudio for heavy multitasking.

The HP True Vision 1080p FHD IR camera has a privacy tilt and supports Windows Hello. White wireless keyboard and mouse are included, which is a step up from the wired sets in this price range. Windows 11 Pro is a nice bonus for business users who need BitLocker and Remote Desktop.

Two real concerns. Stock is limited, with only 2 units at the time of writing. Some buyers have reported missing power cords in the box, so check carefully when it arrives. The 16GB RAM is soldered, so you can’t add more later.

For the touchscreen and Pro OS at this price, it’s still a strong pick. Just verify the box contents and warranty on arrival.

Who this is good for

Business users, students, and families who want a Windows 11 Pro touchscreen AIO with a wireless keyboard and mouse included.

Casual users who want a big screen to tap and swipe through apps, recipes, or documents.

Who this is bad for

Power users who need to upgrade RAM later. The LPDDR5 is soldered to the board.

Shoppers wanting the latest AI features or newest AMD processors. The 7520U is from 2021.

6. Lenovo ThinkCentre neo 50a 27 Gen 5 — Best for Business

The ThinkCentre neo 50a is built for the office, and it shows. Luna Grey finish, 100Hz anti-glare display, and VESA-mount compatibility make this a serious workstation.

The 8-core Intel Core i5-13420H runs up to 4.6 GHz and handles spreadsheets, browser tabs, and video calls with room to spare. The 16GB of DDR5 is expandable to 64GB, and the 512GB SSD can be expanded to 4TB. That upgradability is rare in the AIO category.

The 27-inch FHD IPS display hits 99% sRGB, 300 nits, and 100Hz. Scrolling through long documents is much smoother than 60Hz panels. For business users, the difference matters during a full day of work.

Connectivity is strong. You get two HDMI ports (one In, one Out), a USB-C 3.2 Gen 2, USB-A 3.2 Gen 2, two USB-A 2.0, Ethernet, and a headphone jack. The HDMI-In is great for showing a laptop screen on a conference room display.

Concerns include the very limited stock (one unit at the time of writing) and a 1-year third-party seller warranty that some buyers have flagged. If you can find it from a top-tier seller, this is the best business AIO in the lineup.

Who this is good for

Small and medium businesses that want a reliable 27-inch Windows 11 Pro AIO with strong upgradability.

Office managers who need HDMI-In for sharing a laptop screen in meetings.

Who this is bad for

Buyers who want immediate Prime shipping from a major seller. The current third-party listing adds risk.

Users who want a touchscreen. The neo 50a is non-touch.

7. HP 27 inch Ultra 7 Touchscreen AIO — Best High-RAM

This HP stands out for one reason: the USB-C docking station in the box. Most AIOs give you a wired keyboard and mouse, and that’s it. This one adds a real dock for connecting a laptop and turning the AIO into a second screen and port hub.

Inside, the Intel Core Ultra 7 155U is a 12-core chip with a built-in NPU for AI workloads. Combined with 32GB of DDR5 RAM and a 1TB SSD, this AIO has more headroom than anything else in our roundup. If you run virtual machines, large datasets, or dozens of browser tabs, you’ll feel the difference.

The 27-inch FHD touchscreen is a standard 60Hz panel. Colors and brightness are fine, but it doesn’t stand out next to the 100Hz IPS options from Lenovo and HP. The included Free Web Office saves you a Microsoft 365 subscription if you don’t need full Office features.

Two real issues. The webcam doesn’t have a built-in microphone, so you’ll want a headset for calls. McAfee comes pre-installed with pop-up ads, and you’ll want to uninstall it on day one. Some Citrix users also report the headphone jack not working in certain setups.

Who this is good for

Power users, IT managers, and business buyers who need 32GB of RAM out of the box and a USB-C dock for laptop connectivity.

Hybrid workers who want to dock a work laptop to the AIO and use it as a second display.

Who this is bad for

Casual users who don’t need 32GB of RAM. The price is high for everyday work.

Anyone sensitive to bloatware. McAfee and its pop-ups are real here.

8. Lenovo 2026 24 inch IdeaCentre AIO — Budget Pick

The Lenovo IdeaCentre 24 inch is the budget pick for a reason. With over 280 reviews and a 4.4-star average, it delivers on the basics without cutting corners where it matters.

The 8-core Intel Core i3-N305 runs up to 3.8 GHz. It’s not a powerhouse, but for browsing, Office apps, and streaming, it’s plenty. 16GB of DDR4 RAM and a 1TB PCIe SSD are excellent for the price. Many laptops at this price ship with 8GB and 256GB.

The 23.8-inch FHD IPS display hits 99% sRGB and 250 nits with anti-glare coating. For an entry-level AIO, color accuracy is solid. The panel is not the brightest, but for a home office with controlled lighting, it’s fine.

Connectivity is reasonable. Wi-Fi 6, Bluetooth 5.2, Gigabit Ethernet, two USB 3.2 Gen 2, two USB 2.0, HDMI 1.4b, and a headphone jack. The TPM 2.0 chip adds a layer of security for business use.

The main compromise is the included peripherals. The wired keyboard and wireless mouse feel basic, and the system uses Intel UHD integrated graphics, so light gaming is possible but nothing demanding. For everyday home and student use, this AIO punches above its weight.

Who this is good for

Students, first-time PC buyers, and home office users who want a complete Windows 11 AIO without overspending.

Anyone who values 1TB of SSD storage at a low price, since most AIOs at this tier ship with 256GB or 512GB.

Who this is bad for

Gamers and creative professionals. The integrated graphics and modest CPU are not built for heavy 3D work.

Users who want a 27-inch screen. The IdeaCentre here is 23.8 inches.

What to Look for in an All-in-One Computer

Buying the best all in one computers comes down to a handful of decisions. Here is the framework our team uses when we test AIOs.

Display size and quality

Most AIOs ship with 23.8-inch or 27-inch panels. A 27-inch screen gives you more room for side-by-side documents, while a 24-inch model is easier to fit on a smaller desk. Look for IPS over TN for better viewing angles, and check the sRGB coverage if you edit photos.

Refresh rate is starting to matter. 100Hz panels from Lenovo and HP make scrolling noticeably smoother. If you spend 8 hours a day in front of your screen, that is a real upgrade.

Processor performance

For office work and browsing, an 8-core chip like the Intel Core i3-N305 or AMD Ryzen 5 7520U is plenty. For content creation or running virtual machines, step up to an Intel Core i7, Core Ultra 7, or AMD Ryzen AI 7.

AI-ready chips (Intel Core Ultra, AMD Ryzen AI) include a Neural Processing Unit for on-device AI tasks. The software support is still maturing, but you are buying headroom for the next 3 to 5 years.

RAM and storage

16GB of RAM is the new minimum for a smooth Windows 11 experience. If you can get 32GB out of the box, do it. Look for SO-DIMM slots if you want to upgrade later. Soldered LPDDR5 RAM, like in the HP 27 inch Touchscreen AIO, can never be expanded.

For storage, 512GB is the minimum and 1TB is comfortable. Many budget AIOs now include 1TB SSDs, which is a big improvement over the 256GB drives common a few years ago.

Ports and connectivity

Count the ports before you buy. Most AIOs include 3 to 5 USB ports, but the mix of USB-C and USB-A matters. USB-C is essential for modern laptops and docks. HDMI-In is rare but useful for connecting a game console or another computer to the panel.

Wi-Fi 6 or Wi-Fi 6E is the standard now. Bluetooth 5.0 or higher is fine for wireless keyboards, mice, and headphones. Ethernet is a bonus for offices and unreliable Wi-Fi setups.

Upgradeability and repair

This is where AIOs differ most from tower desktops. Most AIOs cannot be opened easily, and RAM is often soldered. The Lenovo ThinkCentre neo 50a and Lenovo IdeaCentre 27 inch i7 are notable exceptions with expandable RAM and storage.

Forum feedback from Reddit and PCMR consistently flags upgrade difficulty as the main downside of AIOs. If you plan to keep your computer for 6+ years, an upgradeable model will save you money.

Mini PC alternative

For the same money, a mini PC plus a separate monitor can give you more power, more ports, and easier upgrades. If repairability matters more than a clean desk, consider pairing a quality 27-inch monitor with a mini PC instead of an AIO.
