I've touched one of these systems.  The airflow seemed quite adequate,
it's the traditional front to back airflow.

One turbine fan keeps the case cool, 2 turbine fans go into a duct that
keeps the air cool until it gets directly injected into the 2 cpu's, which
then of course exhasuts into the case.  The 4th fan injects air into
the power supply.  I couldn't tell if the 4th fan helped the airflow
into the cpu's as well, I didn't take it apart far enough.

In general I was impressed, the air exiting the case was noticably
normal, but less then many other machines.  The airflow in all areas
seemed pretty healthy.

I looked for the original message from Ted Becker but it looked like a
personal email.  I'd like to talk to anyone using these cases, I have
several on order.  I'd be especially interested in exactly what
conditions the failure happened.  Where the paper sleeves removed?  Was
the case open?  Was there a failure or did the bios due a shutdown to
protect itself etc.
