Overview

The LIAN LI O11D MINI V2 is a compact ATX mid-tower PC case that refines the legendary O11 series. With a 10-degree angled bottom panel, this case directs cool air directly to the GPU for significantly improved thermal performance. The front and side feature pillarless tempered glass panels, offering a panoramic view of your build without obstructions. Dimensions of 273mm wide, 424mm deep, and 392mm high make it more desktop-friendly than many full-sized towers, while still accommodating full-size ATX motherboards and power supplies. It occupies a mid-range position in the market, balancing compactness with high expandability and modern aesthetics.

Compatibility Guide

The O11D MINI V2 supports ATX, Micro-ATX, and Mini-ITX motherboards, and is specifically optimized for ATX Back-Connect (BTF) motherboards from ASUS and others. Power supply mounting is bottom-facing, and the protruding mesh side panel allows full-size ATX PSUs up to standard lengths to fit easily. GPU clearance is approximately up to 350mm (check official specs for exact limit), and CPU cooler clearance is around 160mm, accommodating most air coolers and AIO radiators. Drive mounts include a multi-function HDD cage supporting 2.5" and 3.5" drives. The case also includes a 24-pin cable bracket and both horizontal and vertical GPU sag brackets, making cable management and GPU support straightforward.

Product Info

Model number: O11DMIV2X (Black). Released in 2025, with a reference price of approximately ¥30,158 (at Japan). Construction uses alloy steel and tempered glass, with a bottom-mount PSU design. Cooling is air-cooled by default, but the top and side panels can accommodate additional fans and radiators for liquid cooling. Market positioning: mid-range, offering a premium compact experience with panoramic glass, excellent airflow engineering, and rich accessory kit. Warranty is standard 1 year from manufacturer.

Best Use Cases

Compact gaming PC builds: The O11D MINI V2 pairs perfectly with a Micro-ATX board, a high-end GPU, and an AIO liquid cooler to create a powerful yet space-efficient gaming rig. The angled bottom intake directly cools the GPU, essential for hot-running graphics cards. Showcase builds with custom water cooling: The pillarless glass panels provide an unobstructed view of the interior. With included GPU brackets and cable management solutions, you can achieve a clean, professional-looking custom loop or RGB-heavy build. Space-conscious workstation: Use a full-size ATX motherboard and PSU while keeping the footprint smaller than a traditional mid-tower. Ideal for users who need expandability (multiple drives, powerful GPU, large air cooler) but have limited desk space.

Things to Consider

Size limits for high-end components: Despite ATX support, the case is still compact. Very long GPUs (over 350mm) may not fit, especially if front radiators are installed. Tall CPU coolers above 160mm may also conflict with the side panel. Always verify component dimensions against the case's official specs before purchasing. Power supply selection: While full-size ATX PSUs fit, modular or semi-modular units are strongly recommended for easier cable routing in this tight space. Some longer PSUs may limit available space for cable management. No included fans (non-Flow variant): The standard O11D MINI V2 (model O11DMIV2X) does not come with pre-installed fans. You will need to purchase fans separately. Consider the O11D MINI V2 Flow variant if you want pre-installed reverse-blade fans for improved out-of-box performance. Back-Connect motherboard nuance: While compatible with ATX BTF motherboards, the case is not exclusively designed for them; cable routing holes may not align perfectly. For best results, check Lian Li's compatibility list for supported BTF models. Airflow planning required: The case supports bottom intake, side exhaust, and top exhaust configurations. Installing a radiator on top can impede airflow if not balanced correctly. Plan your fan setup before committing to a build.
