I have always lusted after a quad G5. Always. I wish I had one and still do to this day, however I have the two best replacements: a Dual Core 2.0GHz and my most recent acquisition. Every now and again I visit this recycler I meet off of craigslist a few months back and today I decided to make the trip once again. I was hoping to find a 2.3GHz from early-2005 as they always have 10-20 G5s laying around. Sadly, they didn't have any. I ended up walking away with two PPC machines (1.5GHz PBG4 15" and G5) and a hard drive (for my Mac Pro). The G5 seemed like an oddball. It was a 2.5 so I knew it had to have a LCS, but the heat sink seemed different from the Delphi radiator found in most G5s. The factory plastic plug that holds the plate in place was still there so I knew it was never tampered with so all the way I kept trying to figure out what it could be. I never even in my wildest dreams thought that it might end up being a Panasonic LCS. So far I see no leaks, however there is some salt water-like corrosion on some of the metal leading me to believe that this machine was used by the beach. The top CPU is being problematic with the thermal calibration so I need to deal with that tomorrow. Still, after 5-8 G5s, I have never figured out what "TAFFs" are. Temps are staying fairly low at idle: 120-130F for CPU0 120-125F for CPU1 but they max out at 181F (top) and 170F (bottom). The Panasonic definitely looks a lot different then the Delphi!
