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 fans, which provides a 100% improvement over the NZXT H7 Flow in that specific area. While both cases share several identical features, the Phanteks NV5 offers a superior out-of-the-box cooling configuration that distinguishes it from the competition based on the provided data.

Users prioritizing storage capacity should select the NZXT H7 Flow, as it offers a 100% advantage in 3.5" bay support compared to the alternative. Conversely, those who prefer a pre-configured cooling setup should choose the Phanteks NV5 to take advantage of its included fans. Your final decision should depend on whether your build requires extensive hard drive mounting options or a more complete thermal solution provided directly with the chassis.
