Fantastic mATX Case with Impressive GPU Clearance!

This case completely saved my build! I had a very long graphics card that didn't fit into my original setup due to fan clearance issues, but the LIAN LI A3-mATX handled it with ease. I built a compact, high-performance local AI rig using a MINISFORUM BD895i SE motherboard (to reuse my 16x2 DDR and NVMe from a broken mini PC) and an MSI 850W PSU. It offers excellent layout versatility and surprisingly spacious clearance for large GPUs in a small footprint.
