The Lian Li O11 Vision is the objective winner of this comparison, securing five category wins against the two held by the Thermaltake S100 TG. The most significant advantage offered by the Lian Li O11 Vision is its superior maximum GPU length, which provides 37% more clearance for high-end graphics cards compared to the alternative. This makes it the more versatile choice for users prioritizing large hardware compatibility and expansive internal space for their builds.

Users who require maximum room for large graphics cards should select the Lian Li O11 Vision to ensure their components fit without restriction. Conversely, the Thermaltake S100 TG is the better option for builders who prioritize out-of-the-box cooling solutions, as it offers a 100% advantage in the number of included fans. Choosing between these two cases depends entirely on whether your priority is accommodating the largest possible hardware or obtaining pre-installed airflow components.
