MicroATX Mesh Chassis

The Lian Li A3-mATX Black is a steel MicroATX and ITX chassis with mesh side and top panels. It targets builders who want a compact case that still accepts long graphics cards and large radiators. The relocatable power-supply bracket adds layout flexibility for custom loops or air-cooled builds. No side window is included.

Tool-Free Panels and Filter Access

Mesh panels lift off without screws, giving quick access to the interior and the bottom dust filter. The case ships without any pre-installed fans, so the builder must supply and wire all cooling. Cable routing space behind the motherboard tray is tight, so plan the PSU position and cable lengths before final assembly.

430 mm GPU and 360 mm Radiator Headroom

The chassis fits graphics cards up to 430 mm long and CPU coolers up to 167 mm tall. Top, side and bottom mounts each accept a single 360, 280 or 240 mm radiator, while the rear takes a 120 mm unit. Drive capacity is limited to one 3.5-inch bay and two 2.5-inch bays, so storage-heavy builds need external solutions.

Questions about this item

Will a graphics card measuring 430 mm fit without hitting the front panel?

The maximum supported GPU length is 430 mm, so a card of that size will fit as long as the front-mounted PSU bracket is positioned to leave enough clearance.

Can I install a 360 mm radiator on the side panel with fans already mounted?

The side panel supports one 360 mm radiator; fans must be removed or the radiator replaces the fan positions because the mount uses the same 120 mm or 140 mm spacing.

What power-supply form factors are compatible with the movable bracket?

The bracket accepts ATX, SFX and SFX-L units up to 220 mm long, and the bracket can be placed at the front or beside the motherboard tray.
