More specifically, if you are looking to buy a computer rather than build one, Dr. John & company build "hand-crafted PC gaming machines" that are "overclocked and ready to rock" with an extensive 2-year parts and labor warrantythe ultimate back-to-school present. Much better than cookie-cutter boxes from Dell or Gateway.
I should also note that the Celeron 900 wasn't exactly standard fare for the KickAss Gear folks to provide. I remarked to Dr. John that I was surprised how (relatively) slow the Duron was in places, and he replied, "if you think Durons are slow, wait till you bench that Celeron!" He wasn't kidding. I'm sure that's why KickAss Gear doesn't sell Celeron rigs. They usually provide gear that does, in fact, kick ass.
