SNES Motherboard Prototype

I'm attempting to develop a Raspberry Pi 'enclosure' that will allow you to pop a Pi 3 into a gutted SNES case. The final product will have mounting points for power, video and ethernet at the back, a microsd access from the bottom panel, and a GPIO breadboard breakout to run the fan, power light, power and reset switches, and any other modifications a user may see fit.

This object may not be necessary to most people, but I can't stand how messy this inside of my build is so I'm attempting to clean it up. This is my first project so I'm still testing the waters so to speak.
