Ok, so with my imminent purchase of a Mac Pro, something just occurred to me... what about airport? Seeing as I can get the stock MP on eBay for much less, I'm buying one of those, but the stock MPs don't have airport cards (WTF Apple). I'm way out of range of a wired connection where I am in my house, so what should I do? I've read the newer MP's card is different and apparently also voids my warranty, so is there any way around this? I also can't find the airport card for the newer ones for sale anywhere. So, I'm baffled, what can I do?
