In another post, I described the Dual 2.0Ghz machine I just acquired. It has no Airport Card, and I want it to be part of my wireless network. I called OTC and they only have an aftermarket card with an antenna! Where can I get the card that Apple would have put in this machine, had it been ordered that way. Does anyone have a source for this, or a Apple part number for this? Please help if you can!
