I'm suspecting that is lots of CPU but little disk activity?

Based on this, I'd suspect the power supply.  It's hanging on the edge
most of the time, but when the load peaks it just can't handle it.

Of course if the dust issue brought by others is the case, then the
additional thermal load of the increased drive activity could be at
fault.  Do these machines have a thermal cut-out mechanism?  Double
check that all of the fans are running all of the time.
