Very similar in specification to the Best Buy Arbico, Chillblast's Comet uses an Intel Core 2 Duo E8400 processor to achieve a real-world speed score of 115 points in WorldBench 6. This tally has been bettered by both Arbico and Eclipse, but it's a respectable score nonetheless; most users will be unable to notice the difference in performance.

A fairly standard 4GB allocation of RAM and a 250GB hard drive are supplied. The popular 19in Hannspree XM New York monitor also makes its second appearance in our chart, providing the Chillblast Comet with analogue and digital connections and decent image quality.

However, we weren't too impressed by the Chillblast Comet's system case. The TrendSonic is a basic model with two USB ports awkwardly placed at the bottom of the front panel.

Inside, the Chillblast Comet's Asus motherboard leaves little room for expansion, with both memory slots filled and just two expansion slots available.

Neither can the ATI Radeon HD 4650 graphics card match the performance of the HD 4670 supplied by Arbico. In our Crysis tests, the CD 8467 XL was 46 percent faster than the Chillblast Comet. If playing demanding 3D games is important to you, consider the Arbico instead.

Note, however, that the Chillblast Comet is supplied with Vista Home Premium. This OS offers considerably more features than the Basic edition, and the 64bit version found here will let you take full advantage of the Cornet's 4GB memory allocation.

A pair of external speakers is also supplied with the Chillblast Comet. Although you don't get a subwoofer, this setup provides considerably higher-quality sound than the other PCs here, with speakers built into their monitors.

The Chillblast Comet's two-year collect-and-return warranty is the best in this chart.
