It turns out the Apple store folks were a little quick to jump the gun and conclude that the severe crash and refusal to reboot of the G5 PowerMac was due to a mad motherboard.
That's the good news.
The bad news... well, the bad news is that the problem was with the "3rd party memory" that came from our dear sponsor, OWC.
On a positive note, I have already contacted OWC and they are shipping out an advanced replacement pair of chips. I couldn't really ask for more, in that regard.
So in summary... it sucks that the memory went bad, but at least it was memory I purchased from a company that has a good warranty/replacment policy. That makes resolving a situation like this a lot simpler (and less expensive).
Oh, and yes... I'm relieved that I won't need to replace a motherboard and my client won't need to shell out $1000 for same.
Thanks again for your suggestions in dealing with this problem.
Cheers,
Jem
