Hello all, I am soon ordering a PM G5 from eBay but it turns out that not all of the G5s have AirPort built in. After looking through eBay for compatible AirPorts )) and Googling for them, etc. I'm very sonfused as to what exactly I need to make the G5 AirPort compatible. Also, I watched this>> http://www.youtube.com/watch?feature=player_profilepage&v=-kPZjE9mMHw video and I saw that the guy has a Bluetooth antenna and there was a port for a WiFi antenna. So.... how EXACTLY do I install AirPort? Just the card? Or do I also need a plug thingy to go in the back? Also, what AirPort cards are PM G5 compatible, and do they give me Bluetooth as well, or do I need another antenna for that? Thx all very much!
