The Phanteks NV7 is the objective winner of this comparison, securing a lead in four out of eight evaluated specifications. Its most significant advantage is the maximum power supply unit length, which offers 47% more capacity than the alternative. This superior internal clearance provides greater flexibility for housing larger, high-wattage power supplies compared to the Thermaltake S100 TG, which only outperformed its rival in three categories.

Choose the Phanteks NV7 if your build requires extensive room for a large power supply unit to support high-end components. Conversely, opt for the Thermaltake S100 TG if your priority is cooling hardware, as it provides a 100% advantage in the number of included fans. Selecting between these two cases depends entirely on whether you value the increased power supply compatibility of the former or the immediate cooling utility provided by the latter.
