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 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 a clear view of the motherboard, graphics card, and your coolers at the front. Three tempered glass panels provide a panoramic look without an obstructive bar blocking the view.

– 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 240/360 mm radiator in the top panel
– Customizable 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
O11 Vision-M front
Despite its compact size, the O11 Vision-M offers space for Mini-ITX and Micro-ATX motherboards. With five PCIe slots, there is enough 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 install an ATX power supply up to 182 mm in size. 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
Glass on front, side and top
The front, side, and top panels are made of tempered glass. The panels are secured together via a lock-and-key mechanism and do not require additional support in the corners. This makes the interior feel open and gives you a clear view of your components.

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

240/360 mm radiator in the top panel and thoughtful tube routing for AiOs
There is space in the top panel for a 240mm or 360mm radiator. The radiator mount includes integrated tube routing so you can run the tubes of your AiO upwards and over the motherboard. This keeps the GPU, RAM, and showcase area free from crossing tubes.

– 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 sensitive 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
The rear chamber contains 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 altering 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 individual builds, the case offers a changeable layout and a removable cover that visually conceals a top-mounted AiO. The cover is designed 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 swapped out 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 create 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 cohesive.
