Hey guys I've just brought an Early 2008 20" 2.66Ghz, 4GB Ran 2600 Pro to get me started on Mac! I Also have a Power Mac G5 Dual Core Water-cooled Model to play with! just wondering what's the failure rate and reliability for these things? I've seen G3's that are still going strong with no problems? what should i look out for, my iMac is running great, its fast, keeps up with everything havent tried the Power Mac yet as i need a power cord, but when i found out its watercooled for a 10 year old machine i am having doubts... Let me know what you guys think anyway, and if so any problems you have faced or what i can do to look after them!
