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 impactful advantage for the Lian Li O11 Vision is its superior maximum GPU length, which offers a 37% increase in clearance compared to the alternative. This significant spatial benefit provides greater flexibility for housing larger graphics cards within the chassis, establishing it as the more capable option for high-end hardware configurations.

Users prioritizing maximum component compatibility should choose the Lian Li O11 Vision to take advantage of its expanded GPU support. Conversely, those seeking a more immediate cooling solution should opt for the Thermaltake S100 TG, which provides a 100% advantage in the number of included fans. Selecting between these two cases depends on whether your build requires the extra internal length for larger hardware or the convenience of pre-installed cooling components right out of the box.
