hi. sorry for my silly question, but isn't simpler to buy the bcm94360cd? the same that apple uses on their imac 2013 (wireless ac + bluetooth 4.0 with 4 antennas). the only issue is to find the adapter (from apple to mini pci express)
i found this one, selling on taobao online store. they even sell separately the card and the adapter.
i can't find them on ebay, damn it!
