So there's a PM G5 Quad 2.5 that keeps coming up on CL in my area and I really want it but would like some advice before I actually decide to do anything. The seller is offering a 23" Apple monitor(LCD), 4GB RAM, Airport cards installed, bluetooth as well, and including the keyboard(white wireless) wired mouse, and all original system discs as well. It has dual 500GB HDD(one serves as an incremental backup and is essentially a clone of the system). It's running OS X 10.4.3 The only issue that this seller says exists is a "minor fan issue" that "kicks on after some use and is a bit noisy." The price is amazing because no one is buying it and I know that if I contact this guy again then I'm pretty sure that he would hold it for me if I showed interest. I'm just wondering if the fan issue could be a major problem or not. Are there any other concerns with that model PM that I should be concerned with? Thanks in advance for any help!
