Wall mount PC (ver 1.0)

Hi! I was bored one day and decided I wanted to give a new life to an old PC I have at home. I'M AN ABSOLUTE BEGINNER WHEN IT COMES TO DESIGN AND I HAVE NO EXPERIENCE WITH 3D PRINTING, but these are the parts I designed for a wall mounted project in a simple 13mm MDF board which I'll paint. Just a few holes for cable management and that's pretty much it.

(A friend of mine is kind enough to offer to print all these parts for me, as soon as they're printed I'll post photos)
