I did go down to Fry's computer store and bought a few neoprene mats for $4 each. These are made for laptop computers, are about 1/4 inch thick, and are the perfect size for the Outlaw amp. I stacked 3 of the, and now my hot amp is out of the cabinet and in the cool air conditioned air. These mats seem perfect anywhere you want to dampen some vibration.

Thanks, Dan
