Lian Li O11 Vision-M PC case, Micro-ATX, tempered glass, black
The Lian Li O11 Vision-M is a compact mATX PC case for current hardware and a visually appealing showcase build. Thanks to the dual-chamber design, the power supply, drives, and cables remain in the second chamber, while the front gives you an unobstructed view of the motherboard, graphics card, and your coolers. Three tempered glass panels create a panoramic look without a distracting support bar blocking the view.
mATX dual-chamber PC case: Tidy build with a separate chamber
Triple tempered glass: Front, side, and top with lock-and-key mechanism
GPU and slot freedom: 5 PCIe slots and support for graphics cards up to 410 mm long
Airflow & water cooling: Up to 12 fans and a 240/360 mm radiator in the top
Customizable design: Custom layout, cover for screen/LCD, STL file for 3D printing a divider
Lian Li O11 Vision-M mATX case: Space for Mini-ITX, Micro-ATX, and high-end GPUs
O11 Vision-M front
Despite its compact size, the O11 Vision-M offers room for Mini-ITX and Micro-ATX motherboards. With five PCIe slots, there is enough space for a large graphics card. Even long custom designs are no problem: GPUs up to 410 mm in length are supported. In the second chamber, you can fit an ATX power supply up to 182 mm long. There is also space for up to three drives there - ideal for keeping the power supply, storage, and cables out of sight.
Triple tempered glass PC case: Panoramic showcase with lock-and-key
Glass on the front, side, and top
The front, side, and top are made of tempered glass. The panels are locked together using a lock-and-key mechanism and do not require an additional support in the corner. This gives the interior an open look and provides a clear view of your components.
To prevent heat buildup despite the glass top, it features a large mesh cutout. This area is designed to reliably vent warm air upward - especially useful with fans or a radiator installed in the top.
240/360 mm radiator in the top and well-thought-out tube routing for AiOs
There is space in the top for a 240 mm or 360 mm radiator. The radiator mount features integrated tube routing, allowing you to route your AiO tubes upward and over the motherboard. This keeps the GPU, RAM, and showcase area free of hoses running across them.
Airflow in the Lian Li O11 Vision-M: Up to 12 fans for powerful cooling
Up to 12 fans in total (distributed across the main and rear chamber)
Top: 3x 120 mm (or 240/360 mm radiator)
Bottom: 3x 120 mm
Side: 2 fan mounts
Rear: 2 fan mounts
For cooling your hardware, the O11 Vision-M relies on numerous mounting points and a sensible fan layout. At the bottom, you can use 3x 120 mm as intake to supply fresh air directly to the graphics card. At the top, 3x 120 mm can be used as exhaust - or you can install a radiator for CPU water cooling. The side and rear positions allow you to fine-tune the airflow depending on your build.
Rear-chamber cooling with pre-installed fan
In the rear chamber, there is a removable bracket that can simultaneously accommodate 1x 140 mm fan and 2x 120 mm fans. This is useful if you want additional exhaust or targeted airflow in the second chamber without changing the look of the main chamber.
Customizable elements in the O11 Vision-M: Cover, screen options, and 3D-printed divider
Cover with screen option
For custom builds, the case offers a changeable layout and a removable cover that visually conceals a top-mounted AiO. The cover is prepared so that you can neatly integrate either a Lian Li 8.8-inch Universal Screen (sold separately) or another slim display. Alternatively, it can be replaced with a Lian Li 9.2-inch LCD kit.
The screen/LCD options are configured via L-Connect 3, for example for system stats or custom animations, and can also be used as a second display if needed. In addition, Lian Li provides a free STL file for creating a 3D-printable divider. This allows you to visually close the gap between the top edge of the motherboard and the AiO, making your build look even more uniform.
