A customer owns a Dual 1.8ghz PowerMac G5 that has issues. He also bought a stripped G5 containing a working mainboard. I get to take the non-functional mainboard from the original machine and replace it with the one from the second G5.

Sadly the replacement board is from a single processor G5. As long as it works he's happy....

I'm not looking forward to trying to fix this beastie, but it will be a challenge.
