After all that...(See "Bustin’ My Ax Again Fixing an XP Machine" below.)

UPS busted up the PC during shipment! It arrived with a 3" x 6" hole in the box. My son is reporting that the computer is not even getting into post. Diagnostic LED's show the CPU is damaged..which I suspect means the motherboard is damaged. The case was scuffed and flexed out of shape, a screw holding down the motherboard was loose in the case, and the motherboard is bent.

I've already filed a claim online. We'll see where this goes from here.

Very disappointing....
