Compact Open-Frame PC Case — Honeycomb A520M-A II Edition

Focused around the PANORAMA 240 WHITE

This open-frame PC case is designed around the ASUS A520M-A II motherboard, providing a lightweight, airflow-focused platform for compact desktop builds, display PCs, and test-bench-style setups. The layout is clean and minimal, built around a large high-density honeycomb ventilation panel that delivers excellent rigidity and airflow while keeping the print straightforward.

Although this version is tailored for the A520M-A II, additional motherboard configurations will be added in future releases, making this design part of a growing family of printable PC cases.

⚠️ Important Grounding Notice

This is a 3D-printed open-frame PC mount, and the motherboard must be electrically grounded to the PSU (power supply) to operate safely.
Use standard metal motherboard screws and standoffs connected to the PSU ground to ensure proper electrical grounding.
