Hello! my old ibook just died. i'm thinking of replacing it with a used mac mini, and hooking it up around the house to use as a dvd player/internet connection/itunes source. I had a few questions: -the older mac mini's, can i install the airport card from my ibook g4 in the mac mini? -can i use the hd from my ibook (upgraded to an 80 gig) into the mac mini? thanks, r.
