6" Rack, Raspberry Pi 3 Model B - ATX Input

A cabinet for KronBjorn's 6" rack: https://www.thingiverse.com/thing:1936196
Intended to be used with my ATX PSU cabinet here: https://www.thingiverse.com/thing:3352702

Made to house a Pi 3 with an ATX 24 pin power input. I'm intending to power the Pi off of the 5v standby pin and have the Pi turn the ATX supply on via GPIO. I designed this to be mounted upside down in the rack, so the wires going to the ATX plug don't lay on top of the Pi. Here's the pinouts for the ATX supply: http://pinou
