hey, I am newish here and I know another web site that actually forbids talking about hiding grows from people you live with. I don't have an opinion on that, so, I did see a microgrow in one of those tall tower pc's. It measured 2' H x 6" W and 2.5' L and had a 110W CFL inside. It used the regular pc fan for ventilation, so it looked totally stealthy.
