Lian Li O11 Vision Compact E-ATX Mid Tower Case

The Lian Li O11 Vision Compact is a dual-chamber mid-tower PC case designed for builders who want a clean, component-forward aesthetic without sacrificing cooling flexibility. Two swappable top panel configurations let you tailor the chassis to your build: choose the tempered glass top for an uninterrupted panoramic view of your components, or switch to the mesh top panel with its integrated fan bracket for extra radiator or fan mounting options. A key design feature is the concealed AIO tube routing system. AIO pump and tubing can be hidden within the second chamber, keeping the main motherboard area visually uncluttered. This works in harmony with support for back-connect ATX motherboards, which route power and data cables behind the motherboard tray for a remarkably clean interior. Vertical cable grommets run along the right side of the motherboard, with a large top grommet sized to accommodate CPU pump blocks; this grommet is removable for maximum clearance. The brushed aluminium exterior finish and 4mm tinted front and side tempered glass panels give the chassis a premium look from all angles, while the inner corner silkscreen and mounting key—rated to withstand 35 kg of force—provide robust structural support for the glass panels. A built-in, adjustable GPU anti-sag bracket accommodates graphics cards from 278mm to 408mm in length. Cooling headroom is generous: the chassis supports up to 11 fans in standard configuration, or up to 14 fans in mesh-mode push-pull. Fan positions include top (3x 120mm or 2x 140mm), side (3x 120mm), bottom (3x 120mm), and rear (2x 120mm). Radiator compatibility spans 240mm, 280mm, and 360mm across the top, side, and bottom positions. A full-length magnetic bottom dust filter pulls out from the left side for easy cleaning. Storage is handled by two 2.5-inch SSD slots behind the motherboard tray and a removable drive cage supporting two 3.5-inch HDDs or 2.5-inch SSDs. Cable management is aided by dual-layer cable clips, six Velcro straps, and a PSU mounting bracket that extends 15mm rearward to create extra routing space. The front I/O panel sits at the foot of the chassis and includes two USB 3.0 ports, one USB 3.1 Type-C port, a 3.5mm audio combo jack, and an illuminated power button.
