It's something of a miracle that Apple can continue to cram newer (and hotter) components into the tiny space behind the iMac's screen, but we're already ready for a bigger redesign.
The Dell Inspiron 27 7000 is a great looking update to the previous 2017 model. It's still a reasonable price for a student on a budget.
If you're looking for an all-in-one that's going to last you a few years, the HP Envy 32 AIO hits the mark.
While it includes some performance and graphics concessions on the lowest priced model, the 21.5-inch iMac brings Apple's iconic design and top-notch bundled accessories and software to a wider audience.
The already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
The Corsair One Pro offers a stunning balance of performance, size and design.
Dell's workmanlike Inspiron One 2330 won't change your life, but it will meet all of your basic mainstream desktop needs while also providing a few useful extras.
The Apple Mac Mini 2018 continues to serve as a satisfying, gets-the-job-done desktop system that delivers surprising value when you want something designed to be seen and not heard.
Anyone who bought last year's redesigned iMac doesn't need to upgrade, but for owners of older models or anyone looking to switch, the latest 27-inch Apple iMac offers a wide-ranging set of internal upgrades.
Gaming all-in-one desktops are rare, and not for everyone, but the MSI AG270 is a self-contained gaming rig.
The pixel-dense Dell XPS One 2710 is one of the best Windows-based all-in-ones available and, barring a new iMac, an easy high-end recommendation.
Tabletop PCs may not be fully ready for the mainstream, but this coffee-table-size version from Lenovo is fun to use, and doubles as a solid all-in-one desktop.
eMachines ER1402-05 is a strong living-room Nettop among others like it, but it doesn't compete well in the larger picture of living-room entertainment devices like game consoles, media streamers, and video service-equipped Blu-ray players. It's worth a look if you need a desktop of this particular type, but keep shopping if you need a connected living-room media device.
The Studio Hybrid is definitely worthy of consideration, particularly if you're looking for a tiny Media Center PC. It's more expensive than nettops like the Eee Box or Eee Top, and it's difficult to upgrade yourself, but the fact you can customise it to your specific needs makes it a worthwhile proposition
No, this isn't a flux capacitor. It's Maingear's F131, an amazingly engineered PC packed with a custom APEX liquid-cooling block.
The Packard Bell oneTwo may not offer the best touchscreen experience, but its built-in Freeview TV tuner and ability to link games consoles via the HDMI-in port makes it a good choice for a student flat or as a second family computer.
The all-in-one Acer Aspire Z5771 desktop PC offers good performance for an affordable price, making it a wise choice for family computing. The absence of a Blu-ray drive and the lacklustre screen means it won't appeal to movie lovers.
The Asus Tytan CG8890 packs in some of the most powerful components a non-military professional has access to. It can tackle the glossiest games with the sort of cool ease most desktops can only dream of but it does demand £4,000 in return. If you custom built a similar rig elsewhere, you could save yourself a bundle.
