Heatsinks and Thermal Epoxy - ideas?

[10kman]

I am trying to get an idea together for a nice heatsink for my Quark 125, and was wondering about a few things.

Is there any other way to fix the Quark to a heatsink, other than thermal epoxy? Something solid, but something that if I do have an issue, I can remove it and get it serviced without getting scolded by Quark (if they would, I'm not sure, but just wondering).

I couldn't think of anything good unless I made like a complete cradle for the ESC, then just strapped it down, but even then it can move.

Also, can a heatsink be too large? Other than the fact that it just takes up too much room, is there a point of no return?

Gracias......
