What I don't get is that you can clearly see the light leaks in your photos and video. Also you're not fooling anyone here that a sheet of carbon padding is going to remove any smell. Hey, it's a commercial enterprise, I can understand you saying it, just that for the money I would want everything flawless. Do any of the incarnations have a real carbon filter with granulated carbon? Hope I don't sound too critical, you have done well and I love the general idea. Mrred has a good point too. Good luck with it.
stealthbox, little tip on the fans is that they all should be exhaust or for circulation inside the box, intake can be passive at 1.5-2x the size of exhaust hole
