I plan to use this open frame case for my home build. https://cults3d.com/en/3d-model/various/boitier-micro-atx-pc I used Tinkercad to cut the stl into 5 sections because the 3D printer I have is limited to build volumes of 200mm x 200mm x 200mm. I have not made this build yet, as I am waiting on the PETG FDM filament to arrive for me to use. I have the ATX power supply, mATX motherboard, controller card, and drives already. This will live in an ventilated cabinet.
