One Pentium 4 2.4ghz, one fast CD burner (40X +), one 512mb DDR ram stick, one 80gig Caviar HD, one SoundblasterLive PCI, one USB PCI with 2 ports backside and 1 internal hub. Only got the HD and PCI cards to clean and test since all was pulled out of a dumpster (from a prebuilt Compaq piece o crap, so the mobo I left as slag). RAM in my current system runs wonderfully. I love recycling.
