I was wondering if anyone had any experience upgrading to wireless n with the 2007 C2D mac mini. All the guides I have found are about the CD (not C2D) machines. I have seen people say they have, but I have spent about 12 combined hours looking for info on the C2D upgrade with no luck. I was on the verge of picking up the MA668Z/B when I saw this ebay listing (link) that says it won't work on C2D machines. Freaked me out a bit. Hoping to get some advice to save me some headache. These are the cards I'm looking at right now: AR5BXB72 (Just found this card listed on OWC while typing this [link], looks like the one!) bcm94322mc Apple Atheros 9280 (but all these cards on eBay ship from China and are likely bootleg) In the picture of the AR5BXB72 I see 3 little spots on the top. I'm guessing those are the antenna plug ins. Which does the bluetooth go into vs the old wifi antenna and the additional wifi antenna? Does it matter? Also, I can't find much info on the antenna. Is this (link) what I need? I just opened my mac mini for the first time yesterday to upgrade it with 4gb Crucial ram, so I'm not afraid to open up my machine for upgrades. Thanks for any help!
