To power on the PSU, I used an original switch on the back of the PSU (red LED ON) and to start the outputs I used toggle switch (green LED). To print the panels I used black Spectrum PETg with 3 perimeters, so in 1 mm thickness is enough to get a solid body. You can use two options for the body, full cover and short. I also created a variation of the front panel. https://youtu.be/Hjjb_51QcBw
