I have a new G5 dual processor but I didn't buy from the Apple store. Rather than use a USB device (I run a LOT of USB devices!,) I would like to put the bluetooth adaptor inside and use the apple bluetooth antennae port - Apple says that they don't supply the board except when the machine is ordered specially. I would have thought that this was a simple third party board which could be clipped onto the motherboard as an after-thought, but perhaps it is more complicated than that. Would anybody have any idea by chance? and ideally a contact as to where to buy the board and antennae..
