The fans tied to the cpu heat sinks may be too close to the top cover 
for effective air flow/cooling. Measure the air temp at various places 
inside the case when closed and the cpu's operating. Try to get an idea 
of how much airflow is actually moving through the case vs just around 
the inside of the case.

Try placing tangential (cross flow) fans in the empty drive bays and up 
against the front panel and opening up the rear of the case.

The power supply has fans at its front and rear to move air through it. 
The centrifugal blower in the rear corner may not be helping much to 
draw air across the cpu's.  The same principle applies to the enclosure. 
Try to move more air through it vs just around the inside. The cooler 
the components the lower the failure rate.
