hey, I did something similar about two weeks ago. this 33asr did not 
have its pedestal. it was build in a 19" cabinet on a rails so you could 
pull it out. the psu was on the backplate and i wanted it to go under 
the hood. My goal was to make no permanent changes to the machine and 
with some shuffling of the powerresistors and the large capacitor I was 
able to use simple aluminium strips bended on the bottom to hold the 
board in its original clamps in place.
