Compact micro-ATX chassis

The Lian Li A3-mATX White is a Micro-ATX and Mini-ITX case built from steel with mesh panels on three sides. It targets builders who want a small footprint without giving up liquid-cooling options or long graphics cards. No fans are included, so airflow must be planned from the start.

Flexible PSU placement upgrades layout options

The power supply can sit at the front or beside the motherboard, letting the builder choose between GPU length and radiator space. Moving the PSU forward clears room for a 360 mm radiator on the side or top, while the rear position favours a 430 mm graphics card. The jump is worth it when a custom loop or thick AIO is required in a micro tower.

Capacity headroom for drives and cooling

One 3.5 inch bay and two 2.5 inch bays cover primary storage. Top, side and bottom each accept a 360, 280 or 240 mm radiator, though the bottom slot is limited to 280 or 240 mm. A 25 mm fan at the bottom restricts GPU thickness to 61 mm, so three-slot cards fit only with slim fans or a relocated PSU. CPU cooler height stops at 167 mm.

商品問答

What clearance does the 167 mm CPU-cooler limit leave for a top-mounted 360 mm radiator and fans?

The case allows a 360 mm radiator in the top position; total cooler height including fans must stay within the 167 mm maximum.

Which screws or clips secure the PSU bracket when it is moved to the front mounting position?

The PSU bracket uses standard case screws; remove the rear bracket screws, slide the bracket forward, and re-fasten it in the front holes.

How often should the removable bottom dust filter be cleaned in a typical home environment?

Clean the bottom dust filter every three to six months, or whenever visible dust build-up restricts airflow through the mesh.
