Whenever I end up getting my iMac, i am going to get the 3.06ghz model. i was also planning on getting 1tb hard drive, but also want the 12% educational discount which can only be done in store. but instore they wont give me a custom built one. Is there anything any one would recommend. Whether i get 1TB or not, i am also going to get an external USB hard drive. the one i was thinking on getting was this one Its fanless which is important because the computer is in the same room as i sleep in, and i know iMacs are quite so the hard drive should be as well... Any suggestions?
