Have you opened up your Dual 2.7GHz G5 and removed the CPU's to check
for corrosion, or leaks? I have both a dual 2.7GHz and dual 2.5gHz G5
PowerMac and both of them had the beginnings of leaks and considerable
corrosion from the "O" rings, so I took them apart, cleaned off the
corrosion and put them back together. I did not have replacement "O"
rings like I should have, so I used some high heat silicone automotive
gasket maker to augment the "O" rings and hopefully prevent any future
leaks at that location. I know that it was very low tech and a bit of
a hack to do it that way, but I did not want to leave the liquid
coolant system open while I waited for new "O" rings to show up in the
mail and I needed to put the systems back together to re-test the dual
2.5GHz system for someone that wanted to buy it. For some reason,
only one of the two 2.5GHz G5 CPU's is being shown as working in the
"About this Mac" menu item. When I swap the G5's from one side to the
other, it is always the same side that is not working, so both of the
G5 CPU's work and it must be a fault with the Motherboard, or G5
socket that is not working correctly.
Anyway, back to the point of my message. I suggest you check any
liquid cooled G5 Mac computer for leaks and corrosion, before you have
a catastrophic leak and failure that damages the motherboard and PSU
that sits under the G5 CPU's (bad design for a liquid cooled system).

Sure.
And it's "geekier" swapping disks and connecting them... :-D
I was mostly concerned about pci-x and the fan controls. I don't know
if I am getting a hardware test disk with it.
My G5 (2,7 DP) is quite silent.
During normal operations, I can barely hear any noise. Just every
now and
then, fans spin up for some seconds, then stop again.
But it could be the liquid cooling making it much less needy for fans
spinning.
