Just picked up a 2.7GHz PowerMac G5. Typing this post on it now. Pretty much a stock configuration though I had to use the hard drive out of my recently deceased 2.0GHz system Case is in rough condition, inside is dirty so it needs a little cleaning. Everything appears to work though the fans spin up and down (maybe will stop once cleaned?) Since this system had the LCS I am concerned about potential failure. Almost didn't buy it for that reason but for $60 I figured why not? It's the top of the line G5 for single core performance. Upon inspection one of the power supply screws appears to have some corrosion on it. I can't say if it's from a leaking LCS or merely because it has been in storage for a while. What steps can I take to minimize any chance of LCS failure?
