I have recently acquired a PowerMac G5 Dual 1.8Ghz Desktop computer (I have decided to replace my MacBook Pro with this). I have read many articles about leaking G5s, G5s exploding due to the liquid cooling etc. I have heard many different stories ranging from Apple never made 1.8Ghz liquid cooled to all of them made past 2005 before Mac Pros were liquid cooled. And Apple made it hard to tell, and I am not ready to hack apart my G5 to find out what kind it is . Question I have for you guys is, how can I tell that my Mac is air cooled, or if it is a liquid cooled death trap? Thanks in advance.
