Compact Micro-ATX Chassis

The Lian Li A3X.US is a 26.3L micro form factor case built from steel and finished in black. It accommodates Micro-ATX and Mini-ITX motherboards and ships with ten pre-installed 120mm fans for immediate airflow.

Ideal for Dense Air-Cooled Builds

This chassis suits builders who want a small-footprint system with abundant included cooling and support for long graphics cards. It is less suitable for anyone needing multiple 3.5in hard drives or extensive radiator stacks beyond the three mounting zones.

Storage and Clearance Limits

Two dedicated 2.5in trays plus a bottom bay that accepts one 2.5in SSD or one 3.5in HDD provide modest drive capacity. The 415mm GPU length limit and 165mm CPU cooler height ceiling handle most mainstream components while radiator mounts top, side and bottom accept 360, 280 or 240mm units.

Highlights

  • Supports micro-ATX and ITX boards for compact builds

  • 10 pre-installed 120mm fans deliver strong airflow out of the box
  • Top, side and bottom radiator mounts up to 360mm enable flexible liquid cooling

Questions about this item

What motherboard form factors does the A3X.US chassis support?

The case accepts Micro-ATX and Mini-ITX boards, so your existing mATX or ITX motherboard will fit without an adapter.

Will my current graphics card fit inside the 26.3L enclosure?

The interior allows GPUs up to 415 mm long, covering most full-length cards on the market today.

How can I verify the included 120 mm fans are running after I build the system?

Power on the PC and confirm all ten fans spin; the front I/O USB 3.1 Type-C and dual USB 3.0 Type-A ports will also light up when the board posts.
