I've got a question. This morning, I've been schmoozing around MacRumors, catching up on things, and came across a thread (probably not too far down the PPC page) where a user mentioned the shock of opening up his iMac G4 to dust and general filth. I've always wanted to open it up and clean it out, and maybe even upgrade the Ram, but one thing has stopped me. THERMAL PASTE. Never, in my hardware-filled life, have I had to deal with Thermal Paste. The name alone sounds strange. Like denture cream, or Shoe Goo. My question, and a question I'm sure many would like answered; how does this stuff work? I just slap it on the plate, press, and that's that? Can you put on too little or too much? A dot the size of a pea? A quarter? I've heard so many horror stories about the ramifications of not reapplying it, that I've been scared into never opening my G4s. I don't even know where to get it, or where to get a good deal on it.
