Lian Li has unveiled the O11D Mini V2, an updated version of its popular compact PC case. This new iteration addresses user feedback and introduces several key improvements, including support for full-sized ATX power supplies and enhanced cooling options, all within a slightly expanded yet still compact 45-liter footprint. The case is set to launch in July 2025, offering a compelling option for builders seeking a balance of size and capability.
Key Takeaways
- Supports full-sized ATX power supplies through a clever back panel protrusion.
- Features a 10° slanted bottom for improved GPU cooling.
- Accommodates ATX, microATX, and Mini-ITX motherboards, including ATX Back-Connect.
- Offers flexible GPU mounting with included anti-sag brackets.
- The “Flow” version includes five pre-installed reverse-blade fans.
- Repositionable I/O module for user convenience.
Smart Design for Compact Power
The most notable innovation in the Lian Li O11D Mini V2 is its solution for accommodating standard ATX power supplies in a compact chassis. Lian Li achieved this by subtly protruding the back panel by approximately 2mm, a design choice that cleverly avoids increasing the case’s overall width while maintaining its 45-liter volume. This allows for greater compatibility with a wider range of PSUs, a significant upgrade from its predecessor which was limited to SFX and SFX-L units.

Enhanced Cooling and Airflow
Lian Li has also focused on improving thermal performance. The O11D Mini V2 features a 10° slanted internal base, designed to direct airflow more effectively towards the GPU for better cooling. Additionally, the case supports various fan configurations, including three 120mm fans at the bottom, two 120mm fans on the side, and options for top and rear mounting. The “Flow” variant comes pre-installed with five 120mm reverse-blade fans, providing optimized airflow right out of the box.

Versatile Build Options
The O11D Mini V2 offers considerable flexibility for builders. It supports ATX, microATX, and Mini-ITX motherboards, including ATX Back-Connect motherboards for a cleaner aesthetic. Radiator support is also improved, with clearance for up to 360mm radiators at the top and 240mm on the side. The case also includes adjustable anti-sag brackets for both standard and vertical GPU mounting, addressing a common concern for users with heavy graphics cards.
Pricing and Availability
The Lian Li O11D Mini V2 is scheduled for release in July 2025. The standard model will be priced at $89.99, while the “Flow” version, which includes five 120mm reverse-blade PWM fans, will retail for $99.99. This pricing makes the O11D Mini V2 a competitive option in the compact ATX case market, especially considering the included fans in the Flow variant.
