custom Quark case design

[zeropointbug]

I'm kinda stumped on what fin design I should make on the bottom of this. I need to make it so they are durable, so you can strap the heatsink down onto something (FLM chassis for instance), or on the motor mount and use air flow effectively. I'm kinda leaning for serrated fins

Also, I really don't think fans will be needed at all on the thing, with a good fin structure on the bottom. It should keep the FET's very cool and happy, would be able to run all day long.

Does anyone with CNC experience know what the smallest feature (flute/bit) can be machined? Is it 2mm? And what about the end of the bit/flute, are the small ones round or flat, or both?

Thanks for the help.

Here is what I am thinking with an integrated heatsink, it looks pretty good too. Too bad I spent all day designing it when I have to completely redesign it when I get my Quark back (for measurements).
