Here's the cab that I ended up putting together. I doubt she'll be winning a beauty pageant, but I think she'll be able to get the job done.
The dimensions are 1.5'x2.5'x3'. All the seams and cracks have been caulked and the doors a semi-lined with insultation material that takes care of light leaks. This really isn't too big of a deal, but I'll get to that later...
I currently have only one fan installed as an exhaust fan w/ a passive intake hole. It's a 12V that's rated for 190CFM, but I'm running it on a 10V adapter, so I guess-timate it's running @ about 150 for me.
As far as the lighting goes, I have 3 105W, 6200 lumen CFLs. 2x 2700k, 1x 5000k.
There's a ionizer in the cabinet to help with smell control once everything gets going.
Throw in a digital thermometer/hygrometer and there you have it....
