Need help with a dead G5 1.8ghz DP PCIX tower

Last Sunday I snagged a 1.8ghz DP PCIX (8 RAM slot) G5 tower and I finally got around to looking at it. The machine makes a clunk clunk noise when I plug it into a live power strip or disconnect power but otherwise it is dead. No lights on the motherboard that I can see, start switch does nothing (no momentary fans or anything).

The guy who had it said he had it fire up before but went to clean it and it wasn't doing anything and he gave up.

The PS is a AcBel API2fs34 Apple P/N 614-0303 600W max and the 2 fuses inside are good, none of the caps look bloated and no smoke/fire damage I can see.

Any ideas?  Was wondering if the PS is sensing a short or something, maybe the CPUs were not put back in correctly? Wiring looks ok so far.
