The Phanteks NV5 is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most significant advantage is the inclusion of fans, which provides a 100% improvement over the alternative. This feature makes the Phanteks NV5 a more complete out-of-the-box solution for users prioritizing integrated cooling components in their build.

Choose the Phanteks NV5 if you want a case that provides double the fan support immediately upon purchase. Conversely, select the Thermaltake The Tower 300 if your build requires a larger clearance for your hardware, as it offers a 14% advantage in maximum cooler height. Your decision should depend on whether you prioritize the convenience of included cooling hardware or the physical space needed for a taller air cooler.
