Yeah I recommend the test bench, plus the shelving was only like $20. Sturdy, strong and light. Can hold 1 to 2 systems per shelf (with the cases turned sideways). I got it at a local hardware store.

The stackable case is in my sig. It's the same case but with longer feet that can lock into the top of another one.

Now that summer is coming, I have blackout curtains and a portable AC coming. I've already setup an air purifier and a humidifier as well to keep the air semi-decent. The only light in this place will be the flashing miners.
