The Phanteks NV7 is the objective winner of this comparison, securing five category wins against the two held by the Lian Li A4-H2O. The most significant technical advantage belongs to the Phanteks NV7, which offers a 236% improvement in maximum cooler height compared to its competitor. This substantial clearance capacity provides the primary edge for the winning chassis, while the Lian Li A4-H2O maintains a 50% advantage in available 2.5-inch drive bays.

Users prioritizing high-profile cooling solutions should select the Phanteks NV7 to take advantage of its superior cooler height capacity. Conversely, the Lian Li A4-H2O is the better choice for builders who require additional storage density, as it provides a higher count of 2.5-inch drive bays. Choosing between these two cases depends entirely on whether your specific build configuration demands greater vertical clearance for cooling components or increased internal space for mounting storage drives.
