Hey everyone, i'm going to buy a new 15" pb in about a month and was wondering if it was possible to mix and match hardware. I know how on the apple website it gives you pretty much pre-selcted options, like you can have this video card or that one. this hard drive or that one. and they correspond to the PB like the 15" superdrive can only have a minimum of 512 ram and a minimum of an 80 gig hard drive. Is there any way to make is so that i could get the 1.5 ghz processor and not have to put atleast 512 ram and atleast an 80 gig hd and other things as well?
