I probably would have gotten a commercial block, but few of them really seem fit for pelt use. Only the Swiftech's (which aren't cheap either) and perhaps #Rotor's design. But I think I can do better than both with this block... I am hoping for a °C/W of .15 or better with it, which is not unreasonable considering the bigger surface area of a pelt.

I would have picked a heatsink with a better fin ratio, but none would have given me as much room to work with as this one. This is how I came up with size requirements: 40 x 40mm area to be cooled, add 5mm to each side to allow for heat spreading in the baseplate, then add 10mm to each side for the Lexan top to attach to. This leaves 70 x 70mm. I guess I could have gotten away with a lot less if I didn't want a Lexan top. I could have had something closer to 50 x 50mm if I had just decided to solder a copper box top on. But I like working with Lexan, and this way I can remove the top for cleaning.

Anyway, what I was really hoping for was some construction tips. Should I use a table saw to cut the base? Do I need a special blade?
