Well, consider this scenerio:
Room temp is 75F. Case ambient temp is 85F (top partition,
CPUs/RAM/video/etc)
The bottom partition has an air intake in the front, drawing cool air from
the lowest portion of the case. This air is drawn over the hard drives,
through the fan, and then pushed out through the power supply. In this case,
it is very possible that the air in this tube will be cooler than 85F. As
such, some of the latent heat sitting at the bottom of the top partition
will be transmitted through the steel plate and dissipiate into the airflow.
This would not be a huge effect...steel isn't that great of a thermal
conductor, especially with all of the air moving all over. However, the
chance that the reverse would occur--bottom partition warmer than top
partition and transmitting heat into it--is small, and would likely only
happen if the fan is extremely weak or dead, or if there are like 6 10-15k
hard drives down there.
The overall point is that the air moving through the "tube", though warmer
than ambient, will almost assuredly be cooler than the top partition.

I'm willing to believe you, but I don't understand how that would work.
Hot air moving through a tube would draw heat into the tube? If that
works, then woudn't my hot water radiators cool my house?
