One thing that you might consider trying...  Since the outer case is 
aluminum with a large radiant surface area, all you would need is a heat 
conductive conduit to pass the hest "through" the interior rubber 
lining.  I would suggest mounting some heatsinks on the inside of the 
case and attach these directly to the aluminum case.  These would then 
act as "heat collectors" and would suck the heat from the interior to 
radiate it via the exterior surface.

Use the aluminum case itself as a heat sink.  You might even consider 
thermally connecting "hot" components mechanically to the exterior 
case.  Although, you have to be careful of that whereas the harddrive 
could "sing" louder as it would then have a large sounding board.  Use 
the passive collection system I suggested if heat does become a problem 
or the "super quiet" fan is not quiet enough.

Nice workmanship BTW, good job on the package!  :)
