this is my box its 20 x 20 x 47 inches I've just drilled 2 bore holes in the top and attaching comp fans and 3 smaller ones on the lower back wall as passive intake I'm lining will foil (very tight budget) 3/4 of the way up the walls. And ill be fixing my lights in as well on a draw string so I can adjust the high will upload more pics when complete. Just wondering if people like the idea and any other ideas I can throw in.
