IMO there is no other case that is as nice as the G5 PowerMac/MacPro cases are made and it would be quite fitting to use it for a Hackintosh build. I love the bare look of Aluminum and Ti as well. Has anyone successfully used the liquid cooling from a dual 2.7 G5 PowerMac for a custom build? (I really should have looked at mine before posting a question but it's packed away at the moment so I thought I'd ask first.) I can't remember which models were susceptible to leakage but mine has never leaked.
