A mini ITX case I made because I wanted to use a small, spare graphics card I had (quadro 600) and a Pico PSU and couldn't find what I wanted online. It measures 5.0" (to top of handle) x 7.0" x 7.75". I am getting CPU temps of 47°C at idle and 57°C at 100% load across all 4 cores.

I included all source files so you can modify anything to your liking (larger graphics card, card reader, USB slots, etc.) All modeling was done in SW2017 but I included step files that will work with any cad software you use.

Here are my specific parts this case works with:
Gigabyte AB350N motherboard
AMD Ryzen 3 2200 CPU w/ stock cooler
Corsair Vengence RAM (2x8gb)
Crucial 500gb M2 hard drive
Pico PSU
Quadro 600 Graphics Card
12mm Computer Case Power Button

Additional hardware needed to finish the case:
