The Antec Flux Pro is the objective winner of this comparison, securing five spec victories against the two held by the Thermaltake S100 TG. The most impactful advantage for the Antec Flux Pro is its inclusion of fans, which offers a 500% improvement over the alternative. This significant lead in cooling hardware makes it the superior choice for users prioritizing out-of-the-box thermal performance and component density without needing to purchase additional cooling solutions separately.

Users should choose the Antec Flux Pro if they require a comprehensive cooling setup immediately upon assembly. Conversely, the Thermaltake S100 TG is the better option for budget-conscious builders, as it holds a 74% advantage in MSRP. Those who prefer to select their own cooling fans or who operate within a strict initial spending limit will find the Thermaltake S100 TG to be the more cost-effective foundation for their system build.
