I'm a Apple tech. in training, and I wanted to check out the details of the innards of the new Power Macs. I've noticed a couple things that are different in the new logic boards and wanted to discuss: The AGP slot now has a second power connector(?). I put a question mark because I am not sure if that is actually what it is. Also, by the bluetooth module (pretty much the same as what the airport card is, meaning its a small card (module, whatever) that connects through a connection similar to a fan connector, and has an antenna that connects to it exactly like the airport antenna), there is a new fan connector called "external fan connector". Now, that is really confusing. I see that they have taken some steps to solve the high noise problems in the origional MDD's, but why are they adding an external fan connector?? I've never heard of such a thing? And is it really external? They don't show anything else about this as I went through the whole service guide and there is nothing else on the external fan connector. All there is, is the logic board diagram and the ext. fan connector is labeled. Anyone care to discuss? ps.. I would post pictures of the diagrams but I dont think apple would be too happy. I dont think talking about this is bad because if I had bought a FW800 PM, I would notice these things and still point them out. I'm sure I would have no idea what the ext. fan connector was called, but I do, and that's... ok. I hope.
