The internal HD in my iBook G4 bit the dust. Im looking for recommendations for a replacement HD? I would like to get a higher quality internal HD, probably 100-120GB. Im also wondering just how much extra heat a 7200rpm internal HD would create? The HD that came with my iBook (purchased June, 2004), a 60GB (I believe 5400rpm), gets pretty hot, so I have to keep a small fan blowing under the iBook which sits on an iCurve.
