As reported in another thread I'm now the proud owner of a G5 Quad. Because of the reading I've done on this forum, I believe that before I even try to power it on, I should apply new thermal compound and inspect the LCS for leaks. Then I planned on using the Apple Hardware Test disk to recalibrate the thermals (can't remember the actual term used around here for that). This leaves me with a few questions... Am I wrong about any of the above? Is there anything else I should do before powering it up for the first time? Can anyone direct me to a good guide for redoing the paste and checking out the LCS? My usual go-to, ifixit, doesn't seem to have anything helpful. What should I do if I do find the LCS to have leaked?
