Lian Li A3-mATX

The A3-mATX is a 26.3-litre micro-ATX case Lian Li designed with DAN Cases. Three sides are steel mesh; it takes graphics cards up to 415 mm long and four slots thick, CPU coolers up to 165 mm and a 360 mm radiator on the side or top. A relocatable PSU bracket lets an ATX, SFX or SFX-L power supply sit sideways or at the front. No fans are included. Owners praise fitting a large graphics card in a small case and the airflow, and recommend a modular or SFX power supply to keep cables tidy.

A3-mATX steel case in black or white (A3-mATX BLACK / WHITE). The Wood Edition with a wooden front (A3-mATX-WD) and the Glass Edition with 3 mm tempered glass (A3-mATX-WDG) share the interior layout but differ in materials and dust filter arrangement; the later B4-mATX is a separate case.

Owner experiences and issues

  • All five verified-purchase reviews visible on LDLC are positive. Owners say the case is roomy for its size, fitting cards such as an RTX 5070, an RTX 5060 Ti and a three-slot RX 5700 XT, and that the mesh panels give good airflow; one owner fitted nine fans for a Core Ultra 7 system. The PSU bracket is described as well made. On the downside, cable management is hard in the tight space, so an SFX or modular power supply makes it easier. An owner who has built PCs for 25 years calls it the best case they have used.
