After some more research, this is the build I have so far:

VCard: (Recertified) eVGA 256-P2-N516-RX Geforce 7800GT 256MB 256-bit GDDR3 VIVO PCI Express x16
Drive: West Dig Caviar SE WD2000JB 200GB 7200 RPM IDE Ultra ATA100 Hard Drive

Still looking for a decent+compatible Case & PSU. Also, I don't think I'll need additional cooling but I'm not sure. This seems like pretty solid performance for the price, but if anyone has better alternatives I would love to hear them (cheaper for same specs, same price for better specs, etc).
