Picking up a Mac pro 2010 that is the low end 12 core. It has water damage to the logic board. I will be picking it up from a friend once he gets it back from insurance. In the mean time anyone know the part number for a logic board? From my understanding they now have a CPU raiser and a back board and both are consider a logic board? Correct me if I'm wrong. Thanks! Picking it up for free so my investment will be cheaper than picking one up from apple I hope. Thanks!
