Sure thing shov!
I've got a dresser/cabinet thing I had in my room setup as a little veg cab. At first it was just for clones but it evolved. I had to remove a shelf that split the cab in 2 vertically and then put a fan in the back. There's a used 4" muffin fan in there I got for CAD$15.
Dimensions are about 36"W x 17"D x 21"H. There's someone sleeping in my room so I can't measure, but that's pretty close.
Lighting: 10x 27W daylight (5500k) CFLs give my 270W of bright, white light in there and they seem to just love it.
So it didn't cost me much and it works well enough for now... the limited height is it's biggest shortcoming.
