tallestskil, I think that if you buy the card, they'll install it free of charge. they told me they'd do that for me, but no apple store had the card for my mac pro classic in stock
 
You could possibly get one off ebay, but the apple (online at least) store should have the adaptors.

I wonder if a standard PCI adaptor would work/be cheaper
 
I purchased the card at a local Mac Store (NOT an Apple Store) but an authorized Mac Store. $49. I installed it myself, but it was a REAL PAIN IN THE BUTT.
 
connecting the leads?

Yes, it took me atleast 15 mins to get the first one. Wasn't sure how hard to press, and at the point I thought I was going to break the logic board, it snapped in. The 2nd was a little easier after that, but still, it was rather annoying.
 
What's funny is that a few months ago, I was able to bring my brother's '06 MP into the local Apple store to have the Airport Extreme card installed for $44 (installation included). So, I bought a '08 MP Octo on clearance a couple weeks back and now none of the stores seem to stock the part anymore. They wouldn't order the part, either.

So I picked up the card for $49 at J&R and installed it myself. Connecting the tiny wires to the terminals on the end of the card is a PITA and it takes lots of patience. But after about an hour, I was back up and running with Wi-Fi. I'm pretty handy tech-wise, but if you're not comfortable with working in small spaces with delicate wires, I would recommend taking it into an Apple service center to get it installed for a charge. The card itself isn't hard to insert into the socket, but connecting the antenna wires to the card is.
 
Im trying to find from ebay or somewhere else inside europe this card for mac pro 09 quad core but i dont know wich one is the correct, can anyone help pls.

Thanks.
 
If you look around ebay around hard enough and have the patience, a broadcom min pci-e wireless card would work perfectly.

I got mine off of ebay for $3.50 shipped from China a few months ago.
