Sounds like a sweet idea using the frame as a heatsink
It should coup easily with a low wattage tec. I think to many people go nuts using massive TEC's and trying to dissipate the heat, all thats needed as a small tec to coup with the load thats causing the problem. That dsi pro mod works just perfect a 3watt tec does the job just beautify and using the existing passive setup to cool it. This is it here

Extremely nicely done, hope to see some results soon and progress come along. I think this would own any cooler box out there and maybe the cheapest and best solution to date to achieve less noise without breaking the bank and going to extream's. As alot of testing has shown sub zero temps really arn't needed in newer sensors and if this takes the edge off enough it could be the best solution ever
Lol this could become a diy kit if you got the heatsink laser cut or pressed out XD
