They call me SCSIraidGURU because I build this monster of a workstation.

Four x Supermicro five drive SCSI hotswap enclosures for 18 SCSI 36GB drives and two spares.  Two enclosures internal and two external.   The external chassis had a customed built PC Power and Cooling 750W power supply wired to turn on when the light switch was turned on.   My workstations can be shutdown from wall switches on 20A circuits.
