WOW, Water cooling.  On a 4  MRF-154 amp you would have the Mister Coffee
Attachment.

There's always water cooling - solder some tubes onto the underside of 
the heat spreader (before you do the final flattening). No need for 
fancy pure water.

I've always wanted to try soldering a large coffee canister onto the 
spreader, mount the amp upside down and fill the can with water. If the 
diameter is large enough convection should avoid hotspots boiling.
