Brainstorming an enclosure box (laser cut acrylic) to house the ATX power supply and Arduino RAMPS combo on our Makergear PRUSA Mendel – has anyone done a similar project?

I considered building in a 4x20 LCD screen and rotor selector – but I’m not sure at the moment . . .

The MG kit came with a breakout piece that connects the green-black to flick things on without a Motherboard . . . I am envisioning a momentary switch to control on/off to the Printer that goes on the outside of the enclosure.

What would be the best type of power switch to trigger on the ATX power supply that I could mount on the outside of the enclosure?
