Hello everyone. I have always wanted a G4 iMac and just purchased one off eBay for a really great price because the internal speaker is dead and it includes no accessories. I went ahead and purchased a new speaker, power cord, 2GB RAM, an IDE to SATA converter (so I can install a 320GB SATA hard drive I already have), Apple Bluetooth card, and an Airport Extreme card. I did a lot of reading here in this forum and watched many YouTube videos over the disassembly of this computer and it doesn't seem above my experience level. My first question is where exactly do I apply the thermal paste? I saw all kinds of warnings about making sure to apply some but never really saw where. I've never applied thermal paste before. Also, how hard is it to install the Apple Bluetooth card? I found the type that fits this iMac, and I see that it screws onto the bottom of the logic board. Should I expect my iMac to come with the antenna cable for the Bluetooth card pre-installed? Your help is greatly appreciated. I'm so excited.
