Just purchased an early 2009 Mac Pro damaged by the previous owner. Apparently, he forced the CPU into the backplane and bent a pin, shorted out and killed the board. I won the bid on a used board on ebay and if all goes well, I will have $350 invested in a step up from my 1.1. I am not sure what to expect when I reboot. Any advise from anyone with experience in this would be appreciated.
