What reviewers say

PCMag’s review praises the Lian Li O11 Vision Compact for its striking “aquarium” design, expansive cooling options (up to three 360‑mm radiators), and spacious interior that still fits a large GPU and tall CPU cooler. The reviewer notes the case is well‑balanced between aesthetics and performance but points out practical drawbacks: it comes with no pre‑installed fans, only one dust filter on the bottom radiator mount, and the optional glass top excludes a top radiator bracket. Overall, the review recommends the case for enthusiasts willing to invest in additional cooling and cable management.
