O11 Vision Manual: A Comprehensive Guide
This manual details the O11 Vision series, a collaboration with PCMR, offering unobstructed views via columnless designs and modularity.
It covers assembly, maintenance, and upgrades for both the standard and compact versions, ensuring a seamless building experience.
The O11 Vision series represents a significant leap forward in PC case design, born from a collaborative effort between LIAN LI and the PC Master Race (PCMR) community. This partnership aimed to create a case that prioritizes aesthetics, functionality, and ease of building. The initial O11 Vision, followed by the more compact iteration, quickly gained popularity for its striking appearance and innovative features.
Central to the series’ appeal is its emphasis on showcasing internal components. Both models boast tempered glass panels – the original offering three sides of glass, while the O11 Vision Compact features swappable glass and mesh top panels – providing an unobstructed view of the hardware within. This design philosophy, coupled with a columnless interior, allows for a clean and visually appealing build. The series is designed to accommodate a wide range of components, including multiple radiators and large GPUs, making it a versatile choice for both air and liquid-cooled systems.
O11 Vision vs. O11 Vision Compact: Key Differences
The O11 Vision and O11 Vision Compact share a core design philosophy, but cater to different build needs and preferences. The original O11 Vision is larger, supporting up to 3 x 360mm radiators and 5 drive capacities, offering greater flexibility for extensive cooling solutions and storage. It features three sides of tempered glass for a panoramic view.
Conversely, the O11 Vision Compact is a smaller iteration, designed for more space-constrained setups. It supports up to 4 spaces for radiators and 4 drive capacities. A key distinction lies in its swappable top panels – offering options for both tempered glass and mesh for optimized airflow. While both are cable management friendly, the Compact’s smaller footprint necessitates more careful planning. The Compact also features back-connect motherboard compatibility, a feature not explicitly mentioned for the original model.
Collaboration with PCMR
Lian Li partnered with PC Master Race (PCMR) to bring the O11 Vision series to life, blending Lian Li’s expertise in case manufacturing with PCMR’s deep understanding of the enthusiast PC building community.

This partnership ensured the cases were designed with the end-user in mind, prioritizing ease of build and aesthetic appeal. By combining Lian Li’s manufacturing prowess with PCMR’s community insights, the O11 Vision series quickly became a popular choice among PC enthusiasts.
Design Philosophy: Unobstructed Views
The core design philosophy behind the O11 Vision series revolves around providing users with the most unobstructed view of their system’s internal components. This was achieved through a radical departure from traditional case designs, eliminating support columns and pillars that often obscure the view of hardware.
Lian Li utilized triple tempered glass panels (in the original O11 Vision) to create a seamless, panoramic showcase for components. This design choice allows builders to fully appreciate their carefully selected hardware and custom cooling solutions. The columnless design isn’t merely aesthetic; it maximizes the visual impact of the build, turning the PC into a true work of art. The focus is on showcasing the internal components, making them the star of the show.
Columnless Design Explained
The O11 Vision’s signature columnless design is a significant engineering achievement. Traditionally, PC cases rely on internal support structures – columns – to maintain rigidity and support the weight of components like motherboards and graphics cards. Lian Li overcame this challenge by employing a robust frame construction and strategically reinforced tempered glass panels.
This innovative approach eliminates any visual obstructions, offering a truly panoramic view of the internal hardware. The tempered glass panels themselves contribute to the structural integrity, working in tandem with the chassis to provide a stable and secure environment for components. This design isn’t just about aesthetics; it’s about maximizing space and accessibility, allowing for easier installation and maintenance. The result is a clean, minimalist interior that puts the focus squarely on the hardware.
Dual-Chamber Layout
The O11 Vision series features a distinctive dual-chamber layout, a key element in its design philosophy. This separation divides the case into two distinct zones: one for the motherboard, CPU, and cooling components, and another for the power supply, storage drives, and cable management.
This compartmentalization offers several advantages. It improves airflow by isolating heat-generating components, leading to potentially lower temperatures and increased system stability. Furthermore, it dramatically simplifies cable management, concealing unsightly wires within the dedicated chamber, contributing to a cleaner aesthetic. The dual-chamber design also enhances the overall visual appeal, presenting a more organized and refined interior. This thoughtful layout allows builders to showcase their components while maintaining a tidy and efficient build.
Component Compatibility
The O11 Vision cases are engineered for broad component compatibility, catering to a wide range of enthusiast-grade hardware. Both the standard and O11 Vision Compact models support large GPUs, with the standard version accommodating cards up to 455mm in length. Motherboard support includes ATX, Micro-ATX, and Mini-ITX form factors, offering flexibility for different build configurations.
Regarding storage, the standard O11 Vision provides space for up to 5 drives, while the Compact version supports 4 drives. Crucially, both cases excel in cooling support, accommodating multiple radiators – the standard up to three 360mm radiators, and the Compact up to four spaces for radiators. This ensures compatibility with both air and liquid cooling solutions, allowing users to tailor their cooling setup to their specific needs and preferences.
Motherboard Support
The O11 Vision series demonstrates exceptional versatility in motherboard support, designed to accommodate a diverse range of PC builds.
