Hey p1mp send me your invoice via email so I can see the specs on motherboard, etc, I may take them off your hands.
Guys, you're way off if you think $625 was too much or that $400 is too much, new or used. If it's got a GOOD server case and a true server quality motherboard, the combination of both of those is worth $300+. Besides which, he's nonspecific about the exact processor - p4 Dual Core is still very much a good server processor. If it's essentially a desktop motherboard, that changes everything.
Cheers,
Brad
