PC Case Lian Li O11 VISION COMPACT Tower Black

The O11 VISION COMPACT is a smaller collaboration model with PC Master Race (PCMR), derived from the original O11 VISION and based on the O11 Dynamic footprint. It reduces internal volume from 67.8 L to 57.4 L while retaining a focus on flexible layout and component showcase. The compact chassis supports back-connect ATX motherboards, offers swappable top panels (mesh or tempered glass), and includes a removable GPU anti-sag bracket and concealed cable management options to achieve a clean, unobstructed view of installed hardware.

Advantages

The case provides two top-panel options for either high-performance cooling (mesh for top AIO and push-pull fan setups) or broad component visibility (tempered glass for 270° side viewing). Its robust support structure aligns and secures the glass panels with a mounting key rated for significant force, and the chassis is available in black (tinted glass) and white (clear glass with matching fittings). Removable elements such as the side radiator bracket, dust filter, cable management bar and drive cages increase serviceability and layout flexibility.

• Front I/O: power button with white backlight; ports located on the case foot

How to use

Choose the top panel that matches your needs: install the mesh panel for maximum top cooling with AIO radiators and push-pull fan configurations, or fit the tempered glass panel to maximize component visibility. Install the motherboard (including back-connect ATX types) and route cables through the right-side vertical grommets and the large removable top grommet—this allows concealment of AIO tubing in the secondary chamber. Use the removable side radiator bracket for easier radiator and fan installation or reverse it to change airflow direction. Secure the GPU with the pre-installed anti-sag bracket and adjust its height with the rear thumbscrew. Slide out the bottom dust filter for cleaning via the left-side access and remove the magnetic cable management bar or drive cages when extra space is required for routing or components.

Recommendations

For optimal cooling in mesh mode, use a top 360 mm radiator with push-pull fans and plan cable routing through the large top grommet to keep the main chamber visually clean. In vision (glass) mode, conceal AIO tubes in the second chamber and use the back-connect motherboard support to achieve a tidy main display area. Regularly remove the bottom dust filter for cleaning to maintain airflow.
