Power Mac G5 Cooling Systems Leak

The G5 was an excellent processor, but to satisfy Apple's needs for faster CPU, IBM had to push it beyond its limits. As a consequence, Apple had to adopt a liquid-based cooling device for the high-model.
According to a report from a reader from XLR8YourMac, lifetime of this liquid cooling device might become a major issue for Apple and users in a near future. He reports that among the 17 Power Mac G5 2.7GHz units he has in his lab, ALL have their cooling system leaking, leading to the death of the motherboard and processor.
Those units have been purchased at once, and been used in similar conditions. With such a failure rate, one can conclude that at least one series of those Power Mac G5 2.7GHz was faulty. Despite the facts, Apple REFUSED to offer any compensation or special deal to repair or exchange faulty units with Power Mac G5/Mac Pro!! It looks like Apple is actively looking for having another class action targeting one of its hardware.
Owners of Power Mac G5 with liquid-based cooling system should routinely check integrity of the unit by removing the cover and looking for corrosive points or crystals as the first signs of leaks.
