The Phanteks NV5 is the objective winner of this comparison, securing victories in six out of eight evaluated specifications. Its most significant advantage over the competition is the inclusion of fans, which provides a 300% improvement in this category. This substantial lead in cooling hardware makes the Phanteks NV5 the superior choice for users prioritizing out-of-the-box thermal management and airflow configuration without the need for additional component purchases.

Users who prioritize storage capacity should consider the Thermaltake S100 TG, as it offers a 100% advantage in 3.5" drive bays. While the Phanteks NV5 is better suited for builders focused on integrated cooling solutions, the Thermaltake S100 TG is the appropriate selection for those requiring more internal space for traditional hard drives. Choose the former for cooling efficiency or the latter for expanded storage utility based on these specific hardware configurations.
