Lian Li O11 Vision-M PC Case, Micro-ATX, Tempered Glass - Black

The Lian Li O11 Vision-M is a compact mATX PC case designed for modern hardware and an aesthetically pleasing showcase build. Thanks to the dual-chamber design, the power supply, drives, and cables are housed in the second chamber, while you have an unobstructed view of the motherboard, graphics card, and your coolers at the front. Three tempered glass panels provide a panoramic look without any distracting struts blocking the view.

• mATX Dual-Chamber PC Case: Neat layout with a separate chamber
• Triple Tempered Glass: Front, side, and top panels with lock-and-key mechanism
• GPU and slot freedom: 5 PCIe slots and support for graphics cards up to 410 mm in length
• Airflow & Water Cooling: Up to 12 fans and 240/360 mm radiator in the top panel
• Customisable design: Own 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

Despite its compact size, the O11 Vision-M accommodates both Mini-ITX and Micro-ATX motherboards. With five PCIe slots, there is plenty of room 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. Additionally, there is space for up to three drives – ideal for keeping the power supply, storage, and cables out of sight.

Triple Tempered Glass PC Case: Panoramic Showcase with Lock-and-Key

The front, side, and top panels are made of tempered glass. The panels are locked together using a lock-and-key mechanism and require no additional corner supports. This creates an open interior and gives you a clear view of your components.

To prevent heat build-up despite the glass top, it features a large mesh cutout. This area is designed to reliably vent warm air upwards – especially useful with fans or a radiator mounted in the top panel.

Airflow in the Lian Li O11 Vision-M: Up to 12 Fans for Powerful Cooling

• Up to 12 fans in total (distributed across main and rear chambers)
• Top: 3x 120 mm (or 240/360 mm radiator)
• Bottom: 3x 120 mm
• Side: 2 fan slots
• Rear: 2 fan slots

For cooling your hardware, the O11 Vision-M relies on numerous mounting points and a sensible distribution of fans. At the bottom, you can use 3x 120 mm as intakes to provide fresh air directly to the graphics card. At the top, 3x 120 mm fans can be installed as exhaust – or a radiator for CPU water cooling. The side and rear slots allow you to fine-tune the airflow depending on your build.

Rear Chamber Cooling with Preinstalled Fan and Mounts for Three Additional Fans

In the rear chamber, there is a removable bracket that can hold 1x 140 mm and 2x 120 mm fans. This is useful if you want extra exhaust or targeted airflow in the second chamber without altering the look of the main chamber.

Customisable Elements in the O11 Vision-M: Cover, Screen Options and 3D-Printed Divider

For individual builds, the case offers a changeable layout and a removable cover that visually conceals an AiO mounted on top. The cover is prepared so you can integrate either a Lian Li 8.8-inch Universal Screen (sold separately) or another slim display neatly. Alternatively, it can be swapped for a Lian Li 9.2-inch LCD kit.

The screen/LCD options are configured via L-Connect 3, for example to display system values or custom animations, and can also be used as a second display if needed. Additionally, Lian Li provides a free STL file to 3D print a divider. This lets you visually close the gap between the top edge of the motherboard and the AiO, giving your build a more unified appearance.
