Here is a quick 'sketch' of a Quark case idea of mine. I don't have the proper measurements, so it might be off (and is). So now the top FET's would get cooling now, that part about the Quark really bugged me, a heat spreader would almost do nothing for cooling them. The power stage board will be pressed in between the blue plate and the case.
Not all the features I made on it yet, like the slots for the top cover, and slots for two end covers.

Also, I did catch a video of my BL maxx before the Quark died, it was pretty sick for power.
