Looking for advice on small space grow room/box

Hello all.

Noobie looking for advice for a small space. I have space that is approx 32" wide, 19" deep, and over 7' tall. Looks like an unfinished small closet space in the basement.

I'd like to leverage the space for a small setup for personal use. A few plants would suffice. I've looked at the PC cabinets here, and some other small setups, but nothing looks just right.

Money is no object. Ideally, I'd like it to be light sealed for privacy.

Any thoughts on specific threads I should check out? I saw a few rubbermaid container setups that might work, but they were all done "on the cheap", and I am ok with investing more to get better quality results.

Thanks in advance for any advice.

I can fit 30 1 gallon bags in my 2.5 X 5 area. I get anywhere from an 20-50 grams per plant w/ a 600 watt HPS on a mover. I'd go with a 400 hps with an air cooled hood.
