Hello there PPC forum! I just got my hands on a 1.8GHz iMac G5 for the price of FREE thanks to the generosity of a local business. It is seriously an awesome machine. The only "problem" is that it doesn't have blue tooth or airport. Is the card(s) in the 17" iMac G5 1.9GHz(with iSight) compatible with the 1.8GHz and is it fairly simple to do as long as I have the right tools? Thanks in advance for any advice or help!
