This article covers Lian Li O11 Vision Compact White ミドルタワーPCケース.

Overview

The Lian Li O11 Vision Compact is a scaled-down version of the iconic O11 Vision, co-developed with PC Master Race (PCMR). This White variant features three tempered-glass panels on the front, left side, and top, along with a pillarless design that offers an unobstructed view of your components. Despite its compact 57.4-liter volume—roughly 10 liters smaller than the original—it still accommodates Mini-ITX up to E-ATX (280mm wide) motherboards. Whether you’re building a flashy gaming rig or a clean workstation, this mid-tower case delivers both aesthetics and practicality. A standout feature is the interchangeable top panel: you can run it in Vision mode with glass on all three sides, or switch to a mesh panel to mount up to a 360mm radiator on top. The case also supports back-connect ATX motherboards, drastically simplifying cable management. With support for up to 11 fans (8 in Vision mode) and up to triple 360mm radiators (dual in Vision mode), the O11 Vision Compact punches well above its price class.

Compatibility Guide

The case officially supports ATX, Micro ATX, Mini-ITX, and E-ATX motherboards up to 280mm width. Full-size E-ATX (330mm) boards will not fit. PSU mounting is bottom-mount, and standard ATX units are compatible. GPU clearance is a generous 420mm, meaning even the longest current graphics cards like the RTX 4090 will fit with room to spare. CPU cooler height is not officially stated, but typical air coolers up to 170mm and AIO units (280/360mm) are accommodated without issue. Fan support reaches 11x 120mm fans (8 in Vision mode) and radiators up to 3x 360mm (2x in Vision mode). Storage includes two 2.5-inch SSD mounts (accessible via sliding brackets) and two 3.5-inch HDD bays. The bottom dust filter slides out from the left side for easy cleaning. Cable management is enhanced by included dual-layer cable clips.

Product Info

Released in early 2025, the Lian Li O11 Vision Compact White typically retails around ¥15,500 (approximately $110 USD). It comes with a 1-year warranty (via authorized Japanese distributors). This case sits firmly in the entry-to-mid tier segment, offering premium looks and excellent cooling expansion at a very accessible price point. Physical dimensions are 448mm (D) × 447mm (W) × 288mm (H), weight is about 12kg. Materials are steel and tempered glass. Maximum fan/radiator support rivals many larger cases. The back-connect ATX support is a forward-looking feature that will become more relevant as compatible motherboards become mainstream.

Best Use Cases

First, this case is ideal for enthusiasts who want to show off their build. The triple glass panels and pillarless design create a stunning showcase for RGB lighting, custom water loops, or color-coordinated components. Second, builders planning to use back-connect (rear-connector) motherboards will find the O11 Vision Compact perfect—it’s one of the few cases that natively supports this new standard without adapters. Finally, it suits power users who need substantial cooling: with support for three 360mm radiators (in mesh mode), you can comfortably cool a high-end CPU (e.g., Intel Core i9 or AMD Ryzen 9) alongside a flagship GPU, making it suitable for heavy rendering or 4K gaming. ## Alternatives
In the same price bracket, consider the NZXT H7 Flow and Fractal Design Pop Air. The H7 Flow prioritizes airflow with a mesh front panel but lacks triple-glass aesthetics. The Pop Air is quieter and more understated, but its cooling expansion is limited (max 240mm radiator top). The O11 Vision Compact offers superior radiator support (up to 360mm×3) and unmatched interior visibility. If your priority is a showpiece build with great cooling, it wins handily. If you prefer a more minimalist or silence-focused build, the alternative cases may be better.

Things to Consider

The glass panels will show fingerprints and dust quickly, requiring regular cleaning. The pillarless design means there’s no central support column, which might concern some users about structural rigidity—though Lian Li’s build quality is excellent. Remember that E-ATX support is limited to boards under 280mm; wide workstation boards will not fit. Also, when using Mesh mode for top radiators, the top glass panel must be removed, sacrificing the all-glass look for cooling performance. PSU cable routing is straightforward, but very long PSUs (over 180mm) may require careful management. Overall, this case delivers outstanding value for showcase builds but requires a bit more upkeep than a traditional chassis.
