Lian Li A3 mATX (Micro-ATX Tower/Compact SFF Airflow/Optional Mesh or Glass Panels/165mm CPU Clearance) Review
Looking for a small mATX case that isn't a pain to build in, unlike most sub-40L boxes on the market? The Lian Li A3 mATX is built around exactly that problem.
It's one of the few compact cases where you can pull every panel off tool-free and still fit a 280mm AIO up top, so you get SFF looks without SFF-level cable-routing frustration.
Modular Panel System
Every panel, mesh or glass, uses the same mounting points, so you can buy the mesh version and add a glass side later, or vice versa, without swapping the whole case.
Clearance for a Compact Case
335mm of GPU room and 165mm of cooler clearance are generous numbers for anything under 40 liters, putting most mainstream and even a few high-end GPUs within reach.
Comparison to Alternatives
Against the NZXT H5 Flow, the A3 mATX is smaller and drops full ATX support, but its modular panels make it far more flexible to reconfigure later. Against the ASUS Prime AP201, the A3 mATX has more front I/O and a sturdier chassis, though the AP201 is usually a bit cheaper.
