Yes.  It'd be even more important for smaller servers that probably have 
crappier airflow than a large machine.

Yes.  Like I said, the spaces between the machines only serve to act as 
insulation.  Unless you force air through each of the spaces between 
the machines, you might as well stuff them with fiberglass insulation, 
because that's about the same effect that you'll have.
