The NZXT H5 Flow (2024) is the objective winner of this comparison, securing five out of eight total specification categories. Its most impactful advantage over the competition is the inclusion of fans, which represents a 100% improvement in that specific area. By providing superior cooling hardware out of the box, this case establishes itself as the more comprehensive option for users prioritizing thermal management and airflow configuration without needing to purchase additional components separately.

Choose the NZXT H5 Flow (2024) if your primary goal is to utilize a chassis that comes equipped with a higher number of included fans for immediate system cooling. Conversely, select the Thermaltake S100 TG if your build requires significant storage capacity, as it offers a 100% advantage in 3.5" drive bay availability. This makes the latter the more suitable choice for users who prioritize internal hard drive expansion over the cooling hardware provided by the former.
