120mm fan mounts to the side and blows air over the mosfets, you can run it in multiple directions based on what's best for your cooler (thank you GrapeApe for suggesting that it be able to be turned horizontal for big air coolers). And easy access to all the cables.
The plan is that the back-plate will have 2mm of foam (cut out in the same shape as the plate it self to act as a bit of cushion.
I've got to make 10 of these for myself, but once I figure out the effort, laser time & material costs involved I'd be happy to cut some out for others and flat-pack ship them to ya.
Once I have a working prototype I'll snap some pics and have a better of idea of what it cost of others one some.
Can they be screwed together or must they be glued?
