Heres the deal: I have a dual 2.5ghz PM G5 that works fine except that the heat exchanger leaked. Everything else is fine. My question is, I found someone on CL who was selling a quad G5 system for $375 because of a damaged mainboard. Could I take the Mobo from the dual G5 and put it in the case for the quad? The processor sockets are same but I'm unsure as to mounting issues. Any mac techs out there with some experience?
