Lian Li A3 Mesh Micro-ATX PC Case White | G99.A3W.00
The Lian Li A3-mATX White is a compact 26.3L micro form factor PC case developed in collaboration with DAN Cases, combining a minimal footprint with extensive hardware compatibility. Despite its compact size, it supports Micro-ATX and Mini-ITX motherboards, graphics cards up to 415mm long, CPU coolers up to 165mm high, and ATX, SFX, or SFX-L power supplies.
Designed around flexible component placement, the A3-mATX supports up to a 360mm radiator and as many as 10 × 120mm fans, with multiple radiator mounting positions across the top, side, and bottom. Steel mesh top and side panels promote airflow, while removable exterior panels, a relocatable PSU bracket, included GPU anti-sag support, and a removable bottom dust filter simplify building and maintenance.
