If I make kits available the only tools you'd need are a hammer and a screw driver.
I might be interested, contingent upon price of course

BTW, this is super badass, great job!
Add me as a second interested party. Would the kit include the motherboard mounting plate, or would we have to do that ourselves? I know you can buy plates online at various sites for cheap.
I'd rather not modify a bunch of different motherboard types, and have to matching each one to threaded holes in the chasis, so I'm talking with some local sheet metal shops about making up some specifically for the case. If I can get a good price this would be the way to go, because they would all be the same, and designed spefically for our use and have better plate mounting and a real power supply mount.
If that doesn't pan out I'm talking to some recycling outfits in the area the seen interested in processing the computer waste they get and selling me the plates and a price not a lot higher than what they get for scrap.
