I put a small screw in the back and hung one of the power strips. The other one takes different screws for mounting so it's sitting on the ground. My wiring is a mess so forgive me.
I'll eventually mount the other power strip just below the hanging one.
The heater controller is going to likely be mounted to the door just below the power strips.
ATO reservoir didn't fit in the right hand side so it's on the bottom shelf of the shelf next to the tank. I'll be printing a hanger that will hold both the heater controller and the light controller.
I'll also likely have the doser and the dosing reservoirs on the shelf outside the stand OR I'll mount them to the door on the left side - I haven't decided yet.
