There's a flaw in that argument though ... remember, the hard drive is the thing 
generating the heat so not only will the hole be of a different metal than the hard 
drive, it will also be significantly cooler. When I take the hard drive out, its too 
hot to touch whilst the inside of the case at the same time is reasonably warm but 
nowhere near as hot. A hole only gets bigger than the thing in the middle if both the 
hole and the thing in the middle stay at the same temperature or at least maintain 
their temperature difference.

Of course, the point still holds that it should make buggerall difference at the end 
of the day ... especially in my L100 where I can actually wiggle the drive around ...
