I have two PCI-Express-based "Late 2005" PowerMac G5's

One has a 2.0ghz dual core CPU, and is a perfect-looking (new, mint) case.

The other has a 2.3ghz dual core CPU, but it's a scratched up case.

I want to put the 2.3 in the 2.0's case. But I am wondering...

Is the motherboard in these G5's tied down to the CPU it was originally installed with?

Or can one just drop a faster CPU in and have it clock at that faster speed?

Better yet, are all Late 2005 PowerMac G5 power supplies the same power output rating?

I have no problem going through the process of swapping the motherboards and/or power supplies (yes, I have the service manual)...

But then again... it would be ALOT less work if I didn't have to.

Anyone out there ever attempt this?
