Build for dense hardware without sacrificing airflow or presentation. The Thermaltake Tower 300 Snow keeps the vertical Tower Series layout and reworks it into an octagonal prism chassis that stands apart on a desk or in a studio rack environment. It is designed for builders who want room for serious components, not compromises. This case supports a 4090-class graphics card, a standard power supply up to 220 mm, and a 420 mm AIO radiator, giving you the physical space needed for high-wattage CPUs and demanding GPUs. Cooling flexibility is equally strong, with support for up to eight 120 mm or 140 mm fans across the top, rear, PSU cover, and right-side fan bracket. That layout helps maintain airflow across the full system, especially in thermally dense builds. For teams and enthusiasts who care about both function and presentation, the Tower 300 Snow also supports an optional 3.9-inch LCD Screen Kit sold separately. It is a premium enclosure for systems that need clearance, cooling, and a cleaner vertical footprint.
