Where to mount power supply box?

Hi there, I’m finishing my new gen 2 machine assembly and trying to figure out best solution for wiring and mounting both the controller and power supply with the e-stop.

The controller looks easy to mount under the wasteboard, but the power supply box barelly fits under the wasteboard and would require me to drill on the wateboard rails since the holes don’t align. Another problem is the power cable is super short and don’t allow for many options.

Appreciate any ideas and suggestions.

I mounted my RealTime controller on a piece of 1/2 plywood and mounted that to the table frame. My HMI is mounted to the QCW frame with the included arm and mount.
