Mike:
About the dead space at the top of the case: There are accessory fans that
mount in place of an external disk drive; perhaps one of those might help. I
believe that they are sold for the specific purpose of cooling 7200 rpm
drives with outside air, but perhaps one would help in your situation. The
drawback, of course, is that you would lose an external opening in the case.
