How are you planning to provide power to the mainboard? It might be worth considering a supergun or consolize the board with the lions enclosure
Oh, if that is what you are looking for, I have a similar board for my builds. It has solder points for 5v in, a JSTXH connector for RGBS + 5V + GND, but it assumes that you are using a UniBIOS, as select is tied to game-select instead of coin-in:
