Okay, here's a couple pics. Ignore the ScroG screen, I over-vegged, and there was no ScroG'ing those three bushes, got too big. No veg chambers in the cabinet, that just started to feel too complicated to me with ventilation and lightproofing, plus you need all the area you can get when flowering.

The passive intakes are two Doran 8"x8" darkroom louvres (can get them at bhphotovideo.com, probably other places too) at the bottom left, carbon filter's on top hidden behind books and stuff. The second darkroom louvre is mounted in the back wall, bottom left, basically adjacent to the other one on the left side of the cabinet. Cabinet is stealthy enough that I've had people in the same room, didn't notice a thing, although I did turn the fan off for that, as it's hard to disguise the sound of centrifugal fans.

Here's a link to the darkroom louvres. I had to use two to provide enough intake air:
