Are all 3 power supply LEDs on the front panel on?  I understand that
you checked the fuses, but perhaps a power supply failed without
blowing a fuse.

Also, when you say that you hear the disk drives running, do you just
hear the disk spinning, or do you actually hear the head seeking
across the disk (the chunk-chunk-chunk sound)?  All the drives need to
spin is power, but seeking requires that the CPU be running.
