Round 3: build ideas?

So, after two failed attempts, I'm back at it again. The most recent attempt was nearly a success but smelled too strongly to finish flowering. I made a new and improved carbon filter but still feel that the box size and intake/exhaust are a large part of the odor problem. The dimensions of my current box are 17" x 14" x 15", and I have an 80mm (29cfm) intake fan, along with several passive intake holes, and a 120mm (?cfm) exhaust fan which blows out through a carbon filter. The whole unit is located under a large fish aquarium stand. I used four 26 w cfl's with a layer of plexi glass under them to reduce heat. The plants did great only odor was a problem. I plan to rebuild the box with a better size and fan placement (I am willing to buy a more powerful fan/s if necessary.)

Here is what I'm looking for:
-entirely smell proof
-compact/discrete (must fit under aquarium stand- previous box was 17" x 14" x 15", must be same or smaller)
-flower 1-2 plants (with LST and 12/12 lighting from start)
-dry yield inside grow box (no smell)

I know that is a bit picky but I feel that it can be done. I basically am interested in is someone's successful micro grow box plans (especially fan type/placement) that has been verified to be odorless. I'd even be okay using PC grow box plans only making a similarly sized box out of wood instead of using a hollow PC tower. My main concern is odor and specific info regarding air flow/exhaust/intake/carbon filters/etc. Any help would be greatly appreciated, I can give specifications of my old box if necessary. Thanks in advance!

I'd say get rid of the intake fan and stick with passive intake, and combine the carbon filter from your previous grow or an odorsock with ona.
