i mixed and matched some parts from newegg the other week.
AMD 4100 quad core 3.66ghz
4gigs ram.
500gb hd.
$350 + free wireless card.
that's about it really. no fancy graphics card. no amazing hd sound. only game i play is Resident Evil 4 and 5. other than that, i was just tired of my old slow computer and figured i could build a fairly fast one for cheap.
oh and i bought a 5 pack of boxer briefs from target. comfortable.
