Summary: I got a customized one from Dell's site but its basically an XPS 420. It was a great machine, even Vista ran great on it..but about 18 months in the motherboard died. I ordered a replacement from Dell and the shipment has been delayed.
Excerpt: I bought the Dell XPS 420 in March, it was advertised a the PC of the MAC world, a superb machine for gaming, graphics and multi-media. I opted to upgrade the basic to 2Gb of Ram and 500Gb hard drive.
