It consists of (now 7+1spare) 146GB drives in the SuperMicro >SYS-6035B-8B's backplane attached to a LSI22320 . Probably every old timer has a story about chasing a hardware problem where changing the power supply finally fixed it. I keep spares now. If an MCE (which means bad cpu) doesn't go away after changing the cpu it would either have to be temperature, power or a bug in the MCE code.
