PC-behuizing Lian Li A3-mATX micro tower — Micro-ITX/Micro-ATX, Wood & zwart, ondersteunt ATX/SFX/SFX-L-voedingen

The LIAN LI & DAN Cases A3-mATX is a compact micro-ATX mesh PC case that balances a minimal chassis footprint with support for large, high-performance components. The case features a relocatable PSU bracket, modular exterior panels, and multiple mounting options to build a powerful yet space-efficient system. The Wood Edition includes a black walnut trim on the front panel for a refined appearance without sacrificing ventilation.

Advantages

The A3-mATX offers efficient airflow through mesh panels on three sides and a ventilated front, enabling effective cooling in a 26.3‑liter volume. Toolless removal of exterior panels and modular brackets simplifies installation and cable management. Flexible PSU mounting positions, an included anti‑sag GPU bracket and removable dust filter increase build versatility and maintain long‑term cleanliness. The case supports large GPUs and a 360mm AIO radiator while still retaining a compact footprint.

How to use

Plan component placement before assembly: decide PSU position (sideways, front, or offset) based on GPU length and cooling configuration. Remove exterior panels toollessly to access the interior and use modular brackets for straightforward installation of motherboard, storage drives and cooling. Install the anti‑sag GPU bracket to secure alignment for large graphics cards. If fitting a bottom fan, check GPU thickness limitations and adjust mounting positions or use the ATX offset bracket for additional clearance. Fit the removable dust filter on the bottom to keep the system clean.

Recommendations

For high‑end GPU + radiator combos, verify component dimensions (GPU length and thickness, radiator + fan thickness) before purchase; if using a bottom 25 mm fan or a radiator + fan in the bottom position, consider shorter/thinner GPUs or choose alternate mounting positions. Use the Wood Edition front orientation with PSU fan outward to improve PSU airflow.
