  • Beautifully engineered, the Alienware X51 is a quick, small, and surprisingly affordable gaming PC. No competitor can match its killer combo of pint-sized chassis and powerful performance.


  • For those who can afford it as we tested it, the Alienware X51 R2 delivers a premium gaming experience in a compact design that's both stylish and well-suited for the living room. You can also of course configure a less expensive build-out on the Dell Alienware site. Job well done, team AW.


  • The Dell XPS 27 Touch All-in-One (2720) all-in-one desktop updates the best Windows 8 PC around with Intel's latest hardware, and comes up a winner.


  • While we have a few minor quibbles with the Dell XPS 27 Touch's design, we think this is the best all-in-one on the market today.


  • With fresh components, a touch layer, and a much-improved stand, Dell's XPS 27 is the best Windows-based AiO we've seen. With a starting price less than AppleĆ¢??s competing offering, it may gain some iMac converts.


  • Aside from its mostly unnecessary abundance of RAM, the XPS 8700 Special Edition is a well-rounded performance desktop that's a good fit as a family PC or a dorm-room power tower. It's powerful enough to handle pretty much any task that you throw at it, from high-end media creation to high-resolution gaming. And its desktop form factor and upgradability mean it won't have to be replaced as soon as one of the components gets too slow or fails.


  • With an easily accessible, IT-friendly chassis that can pop open without any tools, the Dell OptiPlex 9010 Small Form-Factor is a solid choice for businesses looking to save space without necessarily compromising performance, though more nimble systems in the same price range are readily available.


  • This compact business PC packs a lot of features and performance into not much space and has top-notch warranty, security, and service options.


  • There's plenty to like about Dell's office-bound all-in-one, from its good screen and solid build quality to its powerful performance, at least when it comes to applications. It's not cheap but, if you're after a business all-in-one, the performance and versatility make it worthwhile - just make sure the Apple iMac isn't a better option first.


  • 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.


  • There are more 27-inch all-in-one desktops these days, but very few are done right. The Dell XPS One 27 manages to put almost every technology and feature we're looking for in a compact stylish chassis.


  • Dell has done a fantastic job at putting together a premium 27-inch all in one system with the Dell XPS 27. While the pricing may be a bit high compared to many other all-in-ones, when compared to those with similar features it actually is quite reasonable. Performance is very strong and the display is incredible with its high resolution and bright color. The range of peripheral ports is also quite good for an all-in-one system if you find the need to expand it.
