Hello from Germany!
Inspired by @Colonel69 's design, I created a little Recalbox based on a oneninedesign case myself.
Please note that I cannot recommend this build. I had to remove some GPIO pins (and even had to cut into the black plastics that is holding the pins o_O).
Otherwise, the case looks great and I only hope that my soldering skills were good enough that the resistor (LED) and cables will stick to the switch (which is momentary, btw).
Thanks for the great software!
