My brother-in-laws parents bought a new Mac Mini and as payment for setting it up with all their equipment and giving a basic Snow Leopard class to them they gave me their old desktop computer (no keyboard, mouse, display, or sound system). Its a working P4 tower. Intel P4 at 2.4ghz, 1gb of ram, 1 dvd/cd rom drive, a floppy drive, onboard sound, an Nvidia Geforce FX 5200 128mb video card with VGA and S-video outputs, 4 USB ports, built in Lan 10/100 NIC. The mainboard is an Intel D845EBG2. It has an 80gb IDE HDD. It is currently running XP Pro SP3 with all updates and has the COA. Obviously its not a gaming machine....but it surfs the net just fine and it has 6 unused PCI slots. I'm guessing its worth 50 bucks...gas money for my truck basically.
