The drip feed I was referring to wouldn't be an auto feed system, it'd just be a simple 3 way hydro split (1/4" tubing) with a 1/4" feed that came up to a very small funnel I'd run the water/nutes into. Thus totally eliminating the 5 minute opening/closing of a PC case - However, if your buying a premade case built for growing, then I'm sure they just have very quick thumb releases on the side - but once again, such a small cabinet is built for stealth, so why open it when there is no need?
