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

The Lian Li O11 Vision-M is a compact mATX PC case designed for current hardware and an aesthetically pleasing showcase build. Thanks to the dual-chamber design, the power supply, drives, and cables remain 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 a distracting bar blocking the view.

• mATX Dual-Chamber PC Case: Neat build 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

Despite its compact size, the O11 Vision-M accommodates Mini-ITX and Micro-ATX motherboards. With five PCIe slots, there is plenty of space for a large graphics card. Even long custom designs pose no problem: GPUs up to 410 mm in length are supported. In the second chamber, you can install an ATX power supply up to 182 mm long. 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 from tempered glass. The panels are locked together via a lock-and-key mechanism and require no additional support at the corners. This creates an open interior feel 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 on 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 between 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 many mounting points and a sensible fan distribution. At the bottom, you can use 3x 120 mm fans as intake to supply fresh air directly to the graphics card. At the top, 3x 120 mm fans can be used as exhaust – or a radiator for CPU water cooling. The side and rear fan slots allow you to fine-tune airflow depending on your build.

Rear Chamber Cooling with Pre-installed 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 additional exhaust or targeted airflow in the second chamber without changing 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 a top-mounted AiO. The cover is prepared so you can neatly integrate either a Lian Li 8.8-inch Universal Screen (sold separately) or another slim display. 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 desired. Additionally, Lian Li provides a free STL file to 3D print a 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 cohesive.
