Lian Li's O11D MINI V2 is a compact case with full ATX support

Lian Li's original O11D Mini chassis was widely praised when it debuted, offering a modular design that offered versatile build options and the space to house even the largest desktop graphics cards. The highly anticipated follow-up, the Lian Li O11D MINI V2, has finally arrived - and this time it's got even more room.

With only a minor 2L or 2-liter volume increase over the original, it's enough for the O11D MINI V2 to offer full ATX support for both motherboards and power supplies. Yes, not only is the Lian Li O11D MINI V2 an excellent case for building an M-ATX or Mini-ITX rig with overclocked components, a powerful GPU, and ample cooling, but it also supports full-sized motherboards and power supplies.

However, when it comes to 200mm ATX PSU support, this is enabled with an offset mounting bracket and "side panel protrusion." This is something we noticed when we first saw the O11D MINI V2 at Computex 2025, where, at the time, Lian Li explained that it was due to them sticking to a strict 45-liter limitation for the case.

Anyway, with support for a broader range of off-the-shelf parts, the Lian Li O11D MINI V2 could end up becoming even more popular than the original. The company is also maintaining the line's competitive pricing, with both the black and white variants available now at an MSRP of $89.99.

The O11D MINI V2 remains as versatile as ever, featuring anti-sag brackets for both vertical and horizontal GPU mounting, support for larger 360mm radiators at the top, a relocatable I/O module, and improved GPU airflow thanks to the new slanted bottom.

Full specs and retail links are available below. Lian Li has also launched an O11D V2 Mini Flow variant in black or white that comes with five pre-installed 120mm reverse-blade fans for $99.99.
