I've had this in the back of my head for a while to do something like this. I know these aren't PPC Macs, however many early Intel Macs to me share somewhat of a spiritual likeness due to their similar industrial design as well as the fact that these computers are somewhat "homeless" on MR. For purposes of discussion, I'm including the computers with similar design language to their PPC counterparts-specifically the pre-unibody MBPs and MBs, the Mac Pro(chessegrater), the iMac, and the Mac Mini. I guess we can include the Xserve too for those of you using them. In any case, these computers have a charm of their own. I'm working on getting together a collection of all the variants of pre-Unibody MBP. Aside from that, though, I use a Mac Pro 1,1 on a daily basis. These machines(aside from the MP 1,1) do have their problems, and one of the things I want to do is give sort of a concise location for them. Offhand, one of the big ones is the temperature-related GPU failure on MBPs. Aside from a repaste, one of the things I do on these is run Macsfancontrol and tie the fan speed to the GPU temperature-before the GPU hits 70ºC I have both fans running full blast.
