Ive built it, Check out the journal page in the next couple of days while i get my pics in order. Thanks to CanGroIt for the advise. so far with out my bins being light-proofed, the fan does a great job with passive intake, not even a fan inside for circulation and its still really cool inside the box. Im going to put foil tape around most of the inner part of the bins. and figure something out for the outside if that doesn't do the trick.
Cya later
