Dell Dimension E521 review: Dell Dimension E521

As for Windows Vista on this machine, we can report that it runs well. We didn't notice any obvious compatibility issues with the hardware or the software that Dell sent us. But we did have some trouble with CNET's own multitasking test: It wouldn't run without freezing, which is why there's no chart with those results. Whether that was due to a problem with our test script or something else we can't say, but since an internally generated program was the only thing that wouldn't work, we're not inclined to blame this machine. You can also configure a Dimension E521 with Windows Vista Basic and the Business edition for the same price as an upgrade to Home Premium, although we'd miss the Media Center functions of Home Premium on either of those other versions.

Dell's one year of parts-and-labor coverage of the Dimension E521 is about average for systems in this class. Toll-free phone service is available 24/7, and included onsite repairs improve the outlook. As usual, Dell's Web site is valuable for its FAQs and other information, as well as for its live support chat. As always, we also like Dell's DellConnect service, which lets you turn your PC cursor over to a Dell technician (remotely and with your constant oversight) for remote control assistance.
