Thanks for naming the people who where involved in this.

Great appreciation for doing this and helping the community.
There is one proposal which i would want to make:
Instead of using thermal paste use thermal pads, and place them in the way like this:

Black should be the thermal pad. Red is the area which should not be covered by the thermal pad.

Problem with the thermal paste is that the heatsink actually lies on the red parts and if you tighten the screws too much you risk to crack soldering of those parts. ( I had this on 5 units, which i needed to resolder and from now on i stick only with thermal pads.

I'll recommend this one: http://www.amazon.de/Phobya-W%C3%A4rmeleitpad-XT-1x120x20-wei%C3%9F/dp/B0051C287K
