eh...

1/4" aluminum plate with socket holes and mach 1 hose cutout > mach 1 evaporator head > 1/2" neoprene around the cpu socket with dielectric grease under it ( dielectric grease on the board, cpu pins, etc) > 1/2" neoprene behind mb with dielectric grease > 1/4" aluminum plate with socket holes (tighten down with threads and hexnuts)

Or you can substitute the 1/4" aluminum with 1/4" acrylic.
