1. Product Overview
The LIANLI O11 Vision Compact is a mid-tower PC case designed in collaboration with PC Master Race (PCMR). It offers a compact form factor while retaining the aesthetic and customization options of the larger O11 Vision. This case features a unique pillar-less design with three tempered glass panels (front, left side, and top) for an unobstructed view of your internal components, referred to as 'Vision Mode'. For enhanced cooling performance, the top tempered glass panel can be replaced with an included mesh panel, enabling 'Mesh Panel Mode'.
The O11 Vision Compact is engineered for ease of assembly with modular panels and fan brackets. It also incorporates various cable management solutions to ensure a clean and organized build. The case supports a wide range of motherboard form factors, from Mini-ITX to E-ATX, including back-connect ATX motherboards.

3. Operating Modes and Cooling
3.1 Vision Mode vs. Mesh Panel Mode
The O11 Vision Compact offers two distinct operating modes:
- Vision Mode: Utilizes the tempered glass top panel for a premium, unobstructed view of your components. In this mode, the case supports up to 8 x 120mm fans and 2 x 360mm radiators.
- Mesh Panel Mode: The top tempered glass panel can be swapped with the included mesh panel. This mode enhances airflow and cooling performance, allowing for up to 11 x 120mm fans and 3 x 360mm radiators.

3.2 Airflow Optimization
The dual-chamber design, combined with extensive fan and radiator support, allows for highly optimized airflow configurations. In Mesh Panel Mode, the top exhaust significantly improves thermal performance, especially for AIO liquid coolers mounted at the top.

4. Maintenance
4.1 Dust Filter Cleaning
The case is equipped with a full-length, pull-out dust filter at the bottom. Regularly clean this filter to maintain optimal airflow and prevent dust buildup inside the system.
- To clean, gently pull the dust filter out from the left side of the bottom panel.
- Use a soft brush or compressed air to remove accumulated dust.
- Reinsert the filter securely after cleaning.

4.2 Tempered Glass Cleaning
For cleaning the tempered glass panels, use a microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals that may damage the glass or coatings.
5. Troubleshooting
5.1 General Installation Issues
- Component Fit: Ensure all components (motherboard, GPU, PSU) adhere to the maximum dimensions specified in the specifications section.
- Cable Connections: Double-check all power and data cable connections to ensure they are seated correctly. Refer to your motherboard and component manuals for specific connection points.
- Standoffs: Verify that motherboard standoffs are correctly installed and aligned with your motherboard's mounting holes.
5.2 Overheating Concerns
- Fan Configuration: Ensure fans are installed in the correct orientation (intake/exhaust) to create positive or negative pressure as desired for optimal airflow.
- Dust Buildup: Regularly clean dust filters and internal components to prevent airflow restriction.
- Mesh Panel Mode: If experiencing high temperatures, consider switching to Mesh Panel Mode by replacing the top glass panel with the mesh panel for improved heat dissipation.
