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 already impressive 27-inch 5K iMac gets some welcome spec upgrades for 2017, but rival Windows machines have closed the gap.
Alienware's mid-size Aurora is very flexible, and one of the smallest dual-GPU-ready gaming desktops, but it's still going to hog a lot of floor space under your desk.
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.
A winning design and unusually good sound system highlight HP's first-rate reimagining of the HP Envy Curved AIO 34 for 2017.
For discriminating ears and eyes, the XPS 27 (2017) all-in-one offers the best combination of features for the money.
Apple's Mac Pro has design innovations that we hope will cross over to other systems. Its performance is as strong as you'd expect for a system in its class, and it's priced right, too. You might need more flexibility in your config options, especially for 3D design, but otherwise, the Mac Pro is as solid a professional-class PC as we've seen.
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.
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.
Smaller and less expensive than a Mac Mini, the HP Pavilion Mini focuses on big storage over fast performance.
It starts at $600 (roughly £467 or AU$810), but that configuration may be seriously underpowered.
The refresh for the top-of-the line model of Alienware's Area-51 premium gaming desktop offers more AMD options.
But if you use a webcam, its new midpriced, AMD-powered Inspiron PCs deserve a facepalm.
With bleeding-edge performance and a slew of customization options backed up by support, the Alienware Area-51 Extreme should be on every gamer's short list, as long as you have cash to burn.
As a big-screen upscale all-in-one with touch and decent gaming chops, the latest version of Dell's XPS 27 is a great all-around home PC that covers a lot of bases.
By sacrificing luxuries, the performance-focused Digital Storm Bolt will satisfy most PC gamers for significantly less than most other small gaming desktops.
Sony promises some cutting edge media features on its new Vaio L-Series, but it's tough to recommend when not all of them deliver.
