THERMALTAKE The Tower 100 ITX Mini Tower Cabinet (Snow)

The Thermaltake Tower 100 Snow is a Mini-ITX tower cabinet that brings a vertical chassis design to small-form-factor builds. Part of Thermaltake's The Tower Series, it carries part number CA-1R3-00S6WN-00 and is finished in white SPCC steel. The vertical orientation keeps the desktop footprint compact while the chimney-effect airflow path draws cool air in from the base and exhausts warm air through the top, aided by two pre-installed 120 x 120 x 25 mm turbo fans running at 1000 rpm and 16 dBA each — one at the top and one at the rear. Three 4 mm tempered glass panels wrap around the chassis, offering a panoramic view of internal components from multiple angles. Tempered glass at this thickness is notably more scratch-resistant than standard acrylic alternatives. Magnetic dust filters are positioned at the rear, inner side panels, and inner base to reduce particle ingress and simplify maintenance. Despite its compact profile — 462.8 mm (H) × 266 mm (W) × 266 mm (D) / 18.2 × 10.5 × 10.5 inches, weighing 6.1 kg — the Tower 100 Snow accommodates demanding hardware: CPU air coolers up to 190 mm tall, graphics cards up to 330 mm long, and a standard PS2 PSU up to 180 mm in length. Two 2.5-inch SSDs can be mounted via the side bracket, and two 3.5-inch or 2.5-inch drives can be fitted at the rear when the rear fan is removed. There are two expansion slots for a full-height dual-slot GPU. For additional cooling flexibility, the top position and rear position each support one 120 mm or 140 mm fan, and the top of the PSU cover supports a further 120 mm or 140 mm fan. A 120 mm radiator can be mounted at the top for basic AIO liquid cooling. Front-panel I/O on the top panel includes one USB 3.2 Gen 2 Type-C port, two USB 3.0 ports, and two HD Audio connectors. The modular design allows panels, racks, and brackets to be removed independently, making component installation and cable management more accessible than in many sealed mini-tower designs.
