I don't see any evidence in your post that the liquid cooling design used in the G5's is "poor." Please show me what you consider a good liquid cooling design.
Apple's designed compared to many PC designs is very good. Most of the unit is contained and a user is not apt to knock a component (eg. hose) lose while working on the machine (adding RAM, storage...) The and connectors used are also very strong and offer a good seal. They are much better than those found in almost all other liquid cooling kits.
In short, not only is the design not poor, it's good.
Expecting a liquid cooling design to never have a leak is like expecting no hard drive to ever die. The fact there are failures is a given. So much so, that when I asked about getting Apple Care on my 2.7, many on the forum said it's a good idea with the machines Apple has today. If they were true Apple apologists, do you think they would be recommending that I hedge my bet for when the Apple hardware fails?
MacInTouch has a decent attempt at gauging Mac reliability. http://www.macintouch.com/reliability/
One blurb from it: The total problem percentage for all these Power Mac G5's seemed reasonable at 10%, and even the liquid-cooled Dual 2.5 models (which we thought might be less reliable) looked fine.
