Airhawk,
I've been messing w/ computers for a while now,, sell a few systems now and then out of my house,,,,, If you want the best prices, (and have just a little bit of computer savvy), go to
www.pricewatch.com , there you can pick out whatever you want, and I'll pretty much garuntee the price will beat anyones.

As for system requirements, I'd go with the GeForce4 64 Mg Video without the TV,,,, (have 3 buddies who bought different versions of a TV card,, all had serious problems whenever the card was in there 'puter,,,,,
At least 256Mg RAM,, (I run a GeForce2 32 Mg Video with 640 Mg RAM),
A nice sound card is great with a surround system if your into that, I'm not,, (only ahve the on-board sound)
A 40 Gig HD will do ya, although with the prices now, an 80 Gig is a better buy, (just be sure to partion it into at least 2 drives, preferably more, so that you can back up a complete OS in case of a failure)
OS---G2 will now work with any,,, it had problems in the begining w/ XP, and reg 98,,, but I heard all those glitches are fixed, I run 98SE,, and works fine,

Hope I helped,,,,,
