I received my refurb mac pro yesterday and got it all hooked up to my new NEC 24" monitor and turned it on. Well I started going throught the welcome program and came to realize that Apple didn't install the Airport Extreme Wi-Fi card that was suppose to be included. After a little time with Apple Care, I'm suppose to take the computer to a local Apple certified store and get the card installed. My first question is that I have purchased a bunch of internal HD's and RAM from OWC. Should I go ahead and install those or should I wait to make sure everything is ok with the computer as delivered? Second, should I get the Airport Extreme card or look into another method of internet connection?
