I\'d advise you to stay away from shopping network PCs at any cost. The companies that sell PCs through these channels are among the most untrustworthy con artists I have ever dealt with. A friend of mine ignored my advice and bought an early AMD K7 PC from one of these TV ads about a year and a half ago, and the PC he got was a real piece of cr@p. They use inferior parts whenever possible to lower their costs. Non-ECC memory, a first generation K7 motherboard with a very inferior chipset, a video card that was useless for anything except displaying a low resolution 2D desktop... it goes on and on. They didn\'t even send him everything he was supposed to receive.
I wanted to build a PC for him, but he thought he\'d prefer to buy from a company so he\'d have their tech support. WELL, that\'s sort of useless when they don\'t answer the phone. Now I\'m his tech support after all, and he\'s lucky he has me. Most people who buy these PCs don\'t get any tech support at all. I had to replace several components and reinstall the OS in order to get the damn thing anywhere near stable.
If you don\'t believe me, just look up the company on one of the online rating services like
