This is a original design I made for a Mini ITX motherboard I had laying around.

The current design is (as far as I'm concerned) only suitable for low TDP processors due tot missing fans. I use a ARM in this one, the motherboard doesnt take more than 14 watts of power and has external PSU.

Feel free to customise it to implement your own needs (Pico PSU, Power/Reset Buttons, Sidepanel Logo, Fan screw holes, SSD mounting locations, turboflaps, etc.). FreeCAD file is included.

Print is finished with only 2 print plates (~10 hours total)

Motherboard screws directly into the plastic with standard PC M3 screws (fine thread), no seperate standoffs necessary.

Sidepanel needs 4xM2 screws (Tapered).

Due to the size, this is not suitable for printing on A1 Mini.

To be clear: this is not a Apple PowerMac G5. This is a creative interpetation. None of the measurements of the Apple product have been used.
