  • The Tower 100 Mini Chassis is a vertically-designed mini ITX tower.
  • The chassis is available now starting it $89 from Thermaltake.

Just in time for CES 2021, Thermaltake launched its new Tower 100 Mini Chassis. It's a vertically-designed mini ITX tower with a tempered glass front panel. Its side panels are vented steel, which helps improve airflow while giving it a sleek look. The Tower 100 Mini Chassis is available in black for $90 or snow (white) for $100.

While the Tower 100 Mini Chassis is a mini ITX case, Thermaltake points out that it's not the smallest one on the market. The company designed the case with a bit more room so it can fit high-end components like the NVIDIA RTX 30 series of GPUs. The result is a relatively small case that can still fit in some of the best graphics cards.

The glass panel of the case is triple tempered glass, which is scratch-resistant and thicker than standard panels. The glass panel also shows off any RGB lights that people have as part of their PC build. Around the back of the case, there are removal magnetic fan filters to protect components from dust and dirt.

Heat dissipation is often a concern of smaller PC cases. Thermaltake highlights that the Tower 100 Mini Chassis has cold air intakes and hot air exhausts to help control temperatures. It also supports a CPU color with a maximum height of 190mm.

The tower is 266 mm x 266 mm x 462 mm (10.5 in x 10.5 in x 18.2 in) and weighs 6.1 kg (13.4 lbs). The chassis has two expansion slots, one USB-C 3.2 port, two USB 3.0 ports, and two HD audio ports. It supports a top fan, rear fan, and top of the PSU cover fan.
