Had a similar issue with a PowerMac G5. It was the liquid cooled variant, top specced version, paid around $3500 for it in 2004. Just after the 2 year mark, the o-ring failed and leaked coolant onto the logic board, obviously frying it. It was a documented known issue with the first run of G5s (they changed o-ring manufacturers shortly after they started production), and the o-rings were failing and leaking coolant. Absolutely refused to fix it, wanted $1500 to replace the logic board and the liquid cooling system. I've refused to buy Apple ever since.
