That looks great Griffin! I would love for you to make me one of those clamps for my other Quark that should be here shortly (thanks to AAngel). Looks like it should bleed enough heat away from the top FET's... although, not as well as my clamp.
You see my clamp has to be used with a custom heatsink of some sort, and well, you have seen my Mega Quark, haven't you?
