Updated mITX SFF Chassis - Ghost Clone

I really like the design by Jaxel. I'm creating this remix to improve on the design for building a powerful gaming PC inside.

Redesigned:
- Top & Bottom : bigger ventilation holes with "PC" in morse code pattern. I've split the parts in a different way that makes them easier to glue together when using PETG. 8 degree C reduction versus the original design.
- Bottom: changed the shape of the feet to fit the anti slip feet I still had laying around.

To do:
- redesigning the back case to fit a gpu with backplate
- redesigning the front for usb c + usb 3
- redesigning the side panels for easier gluing and improved ventilation.
