Power Mac G5 and Liquid Cooling System: Part II

First, a report from one of our readers:

... as mentioned in your forum, while we were reporting the problem to Apple Support, and mentioning that the liquid from the cooling system was leaking out, Apple offered to repair the machine for free, even though the warranty was over for months.
To repair this unit, we had to change the CPU, motherboard, PSU and many small materials destroyed by the highly corrosive cooling liquid. Photos illustrate an exceptional case, the cooling liquid leaked slowly out during months, and the Power Mac G5 might have even be working without any liquid in its cooling system.

The main problem seems to be the way Apple Support takes care about such failures. Indeed, for some cases, Cupertino offered to repair for free the faulty computer independently of the warranty, while other readers reported endless discussions with Apple Care to get the cooling system fixed. It looks like Apple defines a number of cooling systems to be exchanged for free, and once reports exceed it, users will have to pay even though it is a clear failure from a component. In EU, Apple should perform the replacement for free, as it will be considered as a hidden vice by a court.
