iMac G5 motherboard repair
Came across this article, from a guy who had one of the infamous Imac G5s with leaky capacitors. He does a step by step guide on how to do your own replacement of said caps.
He even lists the parts you need.
I was impressed. Well done and almost no risk since you have a dead board anyway.
