Summary:
This project turns your PC into a clean, wall‑mounted showpiece.
All critical components – PSU, motherboard, GPU, SSD and power button – are mounted on a square wooden backboard using 3D‑printed brackets and cable guides. The design focuses on minimalist aesthetics and hidden cable routing, so only the hardware is visible, not the mess.

Important: As you can see on the image, I kind of messed up the cable management for the graphics card. There is a cable guide on the right site, but my cables are too short. Make sure you position everything close enough, so that your cables are long enough!
Important 2: The large cable guide is designed to snap around the edge of the wood. Therefore, your wooden backboard must not be thicker than 6 mm. 

Key Features:

• Modular wall‑mounted open frame for desktop PCs (ATX).
• Separate 3D‑printed brackets for PSU, motherboard, GPU and accessories (e.g. SSD, power button).
• Cable guides in different sizes.
• Works with small printer like A1 mini.
• Minimal visible fasteners on the front for a clean, „floating hardware“ look.

Printing & Materials:

• Recommended material: PETG or PLA is just fine
• Layer height: 0.2 mm
• Walls: 4 perimeters
• Infill: 15% (gyroid ) is enough
• Supports: needed for some modells

Assembly Tips:

• You will need some glue for the large cable guide.
• This is not an easy build.
• Your hardware my have different sizes, keep that in mind.
