Lian Li O11 Vision Compact ATX PC Case, Back-Connect, Black (O11VPX) | Compact dual-chamber case with three-panel glass, back-connect support, hidden AIO tube routing and included 360mm top mesh.

The Lian Li O11 Vision Compact (O11VPX) is a masterclass in the "aquarium" aesthetic, delivering an uninterrupted three-sided glass view that eliminates the chunky corner pillars found in traditional cases. Its standout utility lies in its dual-configuration design, allowing you to swap between a panoramic glass top for maximum visual impact or a high-airflow mesh panel that accommodates a top-mounted 360mm radiator. For builders obsessed with cleanliness, the AIO tube concealment feature—which routes tubes into the rear chamber—and native support for back-connect motherboards make it possible to achieve a virtually wireless main cabin.

The trade-off for this visual precision is the total absence of included fans, which adds a hidden premium to your final bill if you intend to fill its 11 fan slots. Furthermore, prioritizing the glass top panel restricts your radiator placement to the side or bottom, and the lack of dust filters on the side intakes means you’ll be cleaning the interior more often than usual. While the compact frame makes cable routing under the GPU a bit tight, these are minor logistical hurdles in an otherwise premium chassis. At an MSRP of approximately $140, you are getting a highly versatile, enthusiast-grade showcase that rivals boutique cases twice its price, making it an easy "buy" for anyone who wants a show-stopping build without the massive footprint of a full tower.
