Best All in One Computers 2026: 10 Ranked, and the i7 Badge That Doesn't Add Up

It takes first place on two numbers. The i3-1215U quotes up to 4.40GHz across six cores, which is above the 3.0GHz turbo claimed on three of the Core i7 listings further down this page. In practice, 78% of its 103 ratings are five-star and another 15% are four-star, leaving 5% at one or two stars.

The rest of the sheet is complete rather than clever: 16GB of LPDDR4, a 512GB SATA SSD, a 3MP pop-up webcam, dual-band AC WiFi, Bluetooth, 2 USB 3.0 ports, 4 USB 2.0 ports, HDMI and a Kensington security slot. Windows 11 Home is pre-installed, and the box includes a wireless keyboard, a mouse and a UK-certified 12V/5A adaptor. The unit weighs 4.2kg and uses a Type G plug.

That said, this is not a machine for editing or gaming. The graphics are integrated Intel UHD, the storage interface is SATA rather than NVMe, and £649.99 is the joint-highest price of the ten for a 23.8in screen. If you want raw multi-core throughput per pound, the £338.81 eight-core machine below beats it on paper.

This is the price outlier. £338.81 buys an eight-core i5-12450H quoted up to 4.40GHz with 12MB of cache, Windows 11 Pro, 16GB of DDR4 and a 256GB SSD. By contrast, the machine in first place costs £649.99 for six cores and 512GB. The trade-off shows up in the ratings: 54% are five-star, but 16% sit at one or two stars.

In practice it is a standard 23.8in curved FHD IPS panel at 1920x1080, an all in one pc for home office, remote work and light gaming as the listing describes it, with 4 USB 3.0 ports, 2 USB 2.0 ports, VGA, HDMI, RJ45 Ethernet, 3.5mm audio, dual-band WiFi 6 and Bluetooth 5.0. Power draw is listed at 65W. A wired keyboard and mouse are included, and the listing also claims fingerprint recognition.

The catch is in the fine print. The spec table lists the power plug as 'Type A - 2 pin (North American)' and the language as German, while the bullet points describe an English (US) QWERTY keyboard. The graphics row names 'Intel Iris Xe Max Graphics' with 2GB, which does not match the integrated graphics described in the text. Either way, check the plug and the keyboard layout before ordering.

This is the storage and software pick rather than the speed pick. £625.39 buys a 1TB SSD, double anything else on the list, plus Windows 11 Pro and Microsoft Office 2021 Professional, both pre-installed and activated. The 29 ratings average 4.2, with 65% of them five-star. The processor is an 8th-generation i7-8700T and no turbo figure is quoted, so it does not enter the 3.0GHz comparison that opens this article.

The build is unusual. It is a mini PC mounted on the rear of a 27in Full HD monitor using the original Lenovo mounting bracket, so in practice you get the look of an all in one desktop with a separate small box hidden behind the panel. Memory is 16GB of DDR4 at 2400 MT/s, and a USB WiFi and Bluetooth adapter is included for wireless. There is a single 2W speaker, which the listing describes as suitable for system sounds rather than music.

Worth noting what is missing from the box. There is no built-in webcam, no keyboard and no mouse, and the spec table lists the power plug type as 'No Plug'. RAM is capped at 16GB, so there is no upgrade path later. If you want a video-call-ready all in one computer with webcam and peripherals included, this is not it.

This one earns its place on capacity, not silicon. £599.99 buys 16GB of RAM and a 512GB SSD with Windows 11, the same memory and storage as the £649.99 model in first place, but the processor description does not hold together. The headline says Intel 13th Gen up to 3.40GHz; the spec table names 'Intel N100' at 3.4GHz, which means the headline and the spec table do not describe the same chip family. Among all in one computers at this price, that row is the first thing to check.

The rest of the package is reasonable: a 23.8in Full HD IPS panel at 1920x1080, a built-in 2MP front camera, dual-band WiFi, Bluetooth, 4 USB 3.0 ports, 2 USB 2.0 ports, HDMI, a Kensington security slot, a Type G plug and a wireless keyboard and mouse. It weighs 5.81kg.

However, the ratings here are the most split of the ten. 56% are five-star, but 22% are one or two star, the highest low-score share on this list. As a result, buy this one only if you can confirm the exact processor model on the page and are comfortable sending it back if it does not match.

A 4.8 average from 14 ratings is the highest score on the list: 90% five-star and 10% three-star, with nothing at one or two stars. Even so, 14 ratings is a thin sample next to the 103 behind the machine in first place, and the price is £649.00, one pound below the top pick, for 8GB of RAM rather than 16GB.

What you get for it is newer memory and newer wireless. There is 8GB of DDR5 with a 16GB ceiling, a 512GB PCIe x4 SSD, Wi-Fi 6, four USB-A ports and an HDMI output for a second display. The 23.8in Full HD IPS screen has three-sided thin bezels and a stand that tilts from -5° to 25°. It weighs 4.3kg, uses a Type G plug, and comes with a wireless EOS keyboard and mouse in Cloud Grey. That is a fuller package than most all in one computers at this price.

In theory, DDR5 and Wi-Fi 6 will age better than the DDR3 machines lower down this list. In practice, an Intel N100 with 8GB is efficiency silicon, and £649.00 is the second-highest price here. If you keep dozens of browser tabs open or edit photos, you are paying top money for the smallest memory allocation of any Windows 11 all in one pc on this page.

This listing and the one further down are the same machine on paper: a 27in Full HD IPS panel, a 43.3cm-to-56.2cm height-adjustable stand, 16GB of DDR3, a 512GB SSD, Wi-Fi 6, Bluetooth 5.3, a privacy webcam and a '16A 5 Pin' plug. Crucially, this one costs £429.00 against £499.98, so you are looking at £70.99 for the same spec sheet unless the panel or the hinge differs in ways neither listing describes.

Ports are generous: HDMI, VGA, LAN, headphone and microphone jacks, plus multiple USB 2.0 and USB 3.0. The processor is a quad-core Core i7 with a turbo frequency quoted up to 3.0GHz, the first of the three 3.0GHz i7 claims on this page. Memory is 16GB of DDR3, two generations behind the DDR5 in the Lenovo above, and the unit weighs 6.9kg. Ratings average 4.6 from 12 reviews, 72% of them five-star.

Worth noting: the operating system is DOS. You supply and install Windows yourself, so £429.00 is not the full cost of a working machine, and the '16A 5 Pin' plug is not the UK Type G fitting. If you want to unbox and start work the same day, look at the Windows listings instead of these all in one computers.

This 27 inch all in one computer shares its stand range, RAM type, storage size and plug type with the £429.00 model: 43.3cm to 56.2cm of height adjustment, 16GB of DDR3 at 2666MHz, a 512GB SSD, DOS, a '16A 5 Pin' plug and a 27in 1920x1080 panel. This one adds a rotatable screen, a 10° upward and 5° downward tilt and a hidden pop-up webcam, and it costs £499.98. Whether the rotation is worth £70.99 is your call.

The processor claim is a quad-core Core i7 with a turbo frequency up to 3.0GHz, the same ceiling as the £359.98 machine at the bottom of this list and the £429.00 model above it. It supports two external monitors at once, and the port list covers HDMI, VGA, USB 2.0, USB 3.0, Wi-Fi 6 and Bluetooth 5.3. Note the weight: 9.73kg, the heaviest of the ten.

That said, you are paying more for the same core specification and an extra 2.83kg over the cheaper twin. DOS means no Windows is included, and 3.0GHz from a processor badged Core i7 sits below the 4.40GHz quoted for the i3-1215U in first place. Skip it if the rotatable screen is not something you will actually use.

This is the cheaper of the two i7-7700HQ machines and, at £369.99 for a curved 23.8in screen, the cheapest all in one desktop computer here with that chip. The processor is quoted up to 3.8GHz, above the 3.0GHz claimed on three of the i7 listings, and it comes with 16GB of RAM and a 512GB SSD. It averages 4.2 from 38 ratings, though 12% of those are one-star.

The rest of the sheet is standard: dual-band WiFi, Bluetooth, 2 USB 2.0 ports, 4 USB 3.0 ports, a LAN port, HDMI, VGA and a wired keyboard and mouse. Power draw is listed at 45W and the unit weighs 4.6kg. The finish is white.

However, three things to weigh up. The system ships with DOS, so Windows is not included at that price. The graphics are listed as Intel UHD 600, which sits at the bottom of the integrated range. And 12% one-star ratings is a higher share than most of the machines ranked above this one.

This is the 27in version of the curved i7-7700HQ idea. £426.99 against £369.99 for the 23.8in model, with the same processor quoted up to 3.8GHz, 16GB of DDR3 and a 512GB SSD. Ratings average 4.5 from 21 reviews and 80% of them are five-star, the joint-best split on this page.

Ports are the fullest on the list: VGA, HDMI, 4 USB 3.0, 2 USB 2.0, a USB 3.0 Type-C, RJ45 LAN and two audio jacks. Wireless is dual-band with Bluetooth 5.0, power draw is listed at 45W, and the unit weighs 7.3kg. A wired keyboard and mouse are included.

The catch is in the wireless bullet. It claims dual-band Wi-Fi supporting '2.8 GHz and the latest 3.8 GHz fast data transmission'. Wi-Fi bands are 2.4GHz and 5GHz; 2.8GHz and 3.8GHz are not wireless bands, and 3.8GHz is the figure quoted for the processor's turbo. Add DOS and DDR3 to that, and these all in one computers are for buyers who read past the bullet points.
