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.
The Corsair One Pro offers a stunning balance of performance, size and design.
The already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
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.
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.
The bold Alienware Alpha makes good on many parts of its promise to meld the gaming PC and living room game console, but there are still too many rough edges to make this a true console killer.
The Toshiba Qosmio DX730 won't win any beauty awards, but it's no dog either. Its bright, Full HD screen, Blu-ray drive and decent performance make it a good option for movie-lovers.
At only 4mm (0.15 inch) at the edge of its Quad HD display and packed with high-end components, the A740 looks like it could be a great desktop -- if you can afford it.
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.
For discriminating ears and eyes, the XPS 27 (2017) all-in-one offers the best combination of features for the money.
The Acer Aspire AU5-620 is a great entertainment PC, pairing an attractive display and strong media-streaming performance with a wallet-friendly price.
Despite its good looks and a few useful new features, Apple's new iMac is all about business. You can find a larger screen for less, not to mention all kinds of digital entertainment features, but no other all-in-one at this price can boast similar performance. If you need a modestly priced all-in-one for getting work done, we'd recommend no other system.
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 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.
The Artisan looks and feels like it belongs in the living room. Performance is similar to all Media Center PCs once you've got them up and running, but the joy of the Artisan is the relative simplicity of its setup. We're never sure what to expect when we sacrifice our living room to a Media Center machine, but this one left us pleasantly surprised
While the higher power consumption is a slight concern, the X4 955 proves that AMD is back in the performance game and ready to play hard ball. Bring on the next generation.
Thanks to 1080p output, TV tuner, Blu-ray player and wall mount, the new TouchSmart blurs the distinction between television and computer even further.
