Cool!
(if you'll pardon the pun)

Great to hear it was rescued. So, how long before they start to appreciate in value I wonder?

I wouldn't expect it to be for a while, if ever, and then only to those interested in old POWER architecture boxes or UNIX iron. Then again, what would I know? The industry moves in mysterious ways.

Yeah, you say that, but it wasn't that long ago that MDD dual 1.42Ghz were all over eBay for $20 or less, I could have had hundreds! (not sure where I would've put them all)

On a side note, aren't the O-rings in the water block changeable?[/QUOTE]

Depends on supply and demand in a particular location as well I suppose. Here, you couldn't give a Power Mac G4 or G5 away, except perhaps to case modders, and even then the demand is slow at best.

Here, G4's you can barely give away, except for the MDD dual 1.42 (now unobtainable here) and the now noticeably appreciating dual 1.2.
G5's are hit and miss, low spec are barely sellable, anything with water cooling is still well over $100, for now. Mid range G5's are a lottery, but not fast sellers.
(Mac Pro 1.1's have come down massively in the last year too)

They most certainly are! Remove 4 screws from the base of each water block, lift the cap, remove the O-ring from the plastic channel they sit in and replace them. Finding the right size can be tricky, but not impossible. I've had companies custom press new O-rings to the correct dimensions for automotive use that would probably work fine in a Power Mac G5.

I wouldn't be surprised if you could even seal the blocks with automotive gasket sealer rated for cooling system use. Wouldn't be as simple of course, but in a bind and being a relatively low pressure system, it would probably do the job.

Can you tell us, where did you get the O-rings made, and how much were they?
