[QUOTE="hype.it, post: 45522, member: 4085"] If the previous models was anything to go by, the piping in the new G5 liquid cooler are made from the same materials such as de-ionized copper or maybe aluminum and not regular rubber or a poly-carbonate or thermal plastics found in common PC systems. If this is the case, there shouldn't be a problem with leakages. Provided that every component passes a strict quality control. In the pass, Apple have always use some sort of silver metal tubing to cooler particular components on the logic board and I expect in the New G5's cooler there is no exception.
