The Phanteks NV5 is the objective winner of this comparison, securing victories in six out of eight evaluated categories. Its most significant advantage over the competition is the inclusion of fans, which represents a 300% improvement in that specific specification. This makes the Phanteks NV5 the superior choice for users prioritizing out-of-the-box cooling configurations and integrated airflow solutions without the need for additional hardware purchases.

Users who prioritize storage capacity should select the Thermaltake S100 TG, as it offers a 100% advantage in 3.5" drive bays compared to the alternative. Conversely, those who prefer a more comprehensive cooling setup should opt for the Phanteks NV5 due to its superior fan inclusion. Choose the Thermaltake S100 TG if your build requires higher internal drive density, or select the Phanteks NV5 for its clear lead in cooling-related specifications.
