The reason I want one is because I have a 300w inverter on my 200w solar panel array. I have the deep cycle battery capable of running one of these for about 6 hours a day without going below 50% of the cell's capacity. Right now I'm just using a gaw fury, and I thought about one of those stick USB setups but they want 80 bucks for 500mh/s (the moonlander).

If I ran this with just a single 2.6mh/s 40chip PCB, that's only about 50 watts. I was thinking I could just rest the pcb on top of the antminer heatsink.

If you look here:

^ All I would have to do is set up a fan or something to blow against the heatsink, so I think this is the direction I'll go.

holes on the heatsink use a standard 92mm fan, and doesn't have to be super-high flow.
Actual power usage is under 45 on all of mine, more like 40 even on the no-fan ones, using bricks I got from Zoomhash.

You need to put a big thermal transfar pad between the PC board and the heatsink and screw them together - that the ONLY cooling the chips get, and they will NOT stay cool without good solid thermal contact.
IMO the termal design of the "blades" was very very poor.

Also check into the threads on litecoin talk and here about adding heat sinks to the regulator circuitry - or UNDERCLOCK the board - that was the biggest fail point on these miner boards.
