I bought a Jabao DC9000 pump or my aquarium, but didn't like the idea of just using a piece of mounting tape to hold the controller. I designed these two brackets for holding the power supply and the controller.
The design for the power supply is to mount it to the underside of the top inside the stand. I just used 4 normal wood screws that fit into the holes. (I'll lookup their size later) I'm also using two cable ties with screws to help hold the cables.
The controller mount is designed to mount on the side of the cabinet.
Edit: I had to redesign the controller mount. It looked nice, but it took too many rafts to print and was a pain to clean up. This one can be rotated to sit on the bottom and shouldn't require any rafts. I also found out the last design wasn't wide enough for the controller to actually fit.The controller is still a bit of a tight fit, but it seems to work.

For some reason Inventor exports .stl files smaller than they should be. You'll want to scale each model by 1000% to make sure they are the right size.
