I was thinking about using this server case, Maxtop CSF-1630B

D X W X H 25" x 17" x 20.8"

That would give me 1 sq/ft per plant, assuming I grew 2 plants. I can make the hydro system so that it sits below the floor of the case (Like a sink basin), so the plants will be able to grow to 18" or maybe even 20".

I'd make the top of the case removable for ease of harvest/trimming.

IF I had enough lighting, would I be able to get 3 plants rocking in that case?
