Hi, I just purchase a refurb 3.0 Ghz 8-core "Clovertown" Mac Pro off of Apple. However it does not come with either an aiport card or bluetooth card. Can anyone help assist me as to which card I would need for this? Does a standard USB bluetooth adapter work, and with the wireless card , this one from apple says its not compatible with the mac pro. http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=7E4EB91E&nplm=M8881LL/A Any help would be greatly appreciated
