The Phanteks NV5 is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most impactful advantage is the inclusion of integrated fans, which represents a 100% improvement over the Lian Li O11 Vision. While both cases share several identical specifications, the Phanteks NV5 provides superior out-of-the-box cooling hardware, making it the more comprehensive option for users prioritizing pre-installed components in their build.

Users who prioritize storage capacity should select the Lian Li O11 Vision, as it offers a 100% advantage in 3.5-inch drive bays compared to the alternative. Conversely, the Phanteks NV5 is the ideal choice for builders who want to minimize additional purchases by utilizing the included fan configuration. Your final decision should depend on whether your specific system requirements lean toward higher mechanical drive support or immediate cooling readiness.
