4 years ago… yeah, I know I’m way out, but I’m trying to put a 2014/15 Mac Mini in a NES. I would like the original Power button to just work ascetically (so it will light up, and that is all. Thinking to run it primarily off of a battery (or possibly a power supply) but not sure what voltage to run it(?).

Any idea what is the positive/negative out of the existing cords (Brown, Yellow, Orange, Red, White)?

Also, I like your project.
