Computer building suggestions?

If you're trying to go a good cheap route, I recommend checking out some of TigerDirect's bare bones systems, which you can get for as little as $199, and then add in whatever other components you prefer. For $200 you could get a Asus M2N68-AM PLUS PowerUp Barebones Kit - Asus M2N68-AM PLUS Mobo, AMD Athlon X2 7850 BE CPU, Crucial 2GB PC6400 DDR2, WD 500GB Caviar Blue HD, PowerUp ATX Mid-Tower Case, 450-Watts Power Supply. That's as good or better on your specs, just drop in your GPU and whatever else you want to add. They have other kits, too, but they start to go more expensive. Good luck with that.
