The Hyte Y40 is the objective winner of this comparison, securing a lead in four out of eight evaluated specifications. Its most significant advantage over the competition is the inclusion of fans, which provides a 100% improvement in that category. By offering a more comprehensive cooling setup out of the box, this case establishes itself as the superior option for users prioritizing pre-installed hardware configurations over other considerations.

The Thermaltake S100 TG remains a viable alternative for budget-conscious builders, as it holds a 67% advantage in MSRP. Users who prefer to select their own cooling solutions or those who prioritize a lower initial cost should choose the Thermaltake S100 TG. Conversely, the Hyte Y40 is the better choice for those who value the convenience and added value of having cooling fans included with their purchase.
