I have a 900 or 950 mhz Athlon system (I forget offhand). I've had it over 1ghz in the past as well.
ECS K7S5A motherboard
40gig Maxtor HDD
Nic, onboard sound
Geforce MX 400 vid card (I think, I can double check for you)
HP cd burner (I wanna say 16x or 24x)
512mb Corsair ram (by far the priciest part, I can pull this if you want the system cheaper)
That should give you an idea of the specs, it's late now, but if you're interested, I can get you exact specs.
If that interests you at all, feel free to make me an offer.
