Here is the ventilation setup I have so far. I will probably be adding something else sooner or later.

Picture 1 - Intake. This fan is huge so it stays on its lowest speed.

Picture 2 - Exaust pic 1.

Picture 3 - Exaust pic 2.

The exaust fan is from Radio Shack. The small vent is a dryer vent I picked up from Lowes. I superglued the fan to the vent and vuola, you have yourself a proper vent. When the exaust fan turns on the dryer vent opens up to release the stinkiness. Funny thing, as small as that little fan is, it kicks some serious ass. I will be adding another one soon however.
