PC Case Thermaltake The Tower 100 Mini Tower Black

The Tower 100 is a vertically oriented mini-ITX chassis with panoramic tempered glass panels. It features three 4 mm tempered glass windows at the front and both sides, two preinstalled 120 mm standard fans (top and rear) for exhaust, and a compact footprint of 462.8 mm (H) x 266 mm (W) x 266 mm (D). The case supports high-end components including long graphics cards and provides versatile storage options while maintaining efficient airflow and removable dust filters.

Advantages

The Tower 100 combines a panoramic view with durable 4 mm tempered glass panels for better scratch resistance and simple access when panels are removed. Magnetic, removable dust filters on the base, inner sides and rear improve dust protection and simplify maintenance. Despite its mini-ITX size, the chassis supports significant hardware: tall CPU coolers, long GPUs and standard PS2 power supplies, while offering flexible cooling options with preinstalled fans and space for additional fans or a 120 mm AIO cooler.

Suitable for

• Compact gaming builds with high-performance GPUs (up to 330 mm length)
• Home or office systems with limited desk space
• Content creators needing a small, displayable system
• Users who prefer tempered glass visibility and modular assembly

How to use

Remove the top panel and tempered glass windows to access the interior for component installation. Mount the Mini-ITX motherboard, install the PSU (up to 180 mm), place storage drives to the designated brackets, and fit the GPU and CPU cooler following the specified maximum dimensions. The preinstalled top and rear 120 mm fans are intended for exhaust; add intake fans or an optional 120/140 mm fan on the PSU cover if additional airflow is required. Reattach glass panels and top panel after cable routing and component checks.

Recommendations

For optimal cooling, keep magnetic dust filters clean and allow at least 20–30 mm clearance around the case for airflow. When using long GPUs or tall air coolers, verify component dimensions against the specified maximums. Use the front and side tempered glass panels to display components while ensuring cables are tidied for unobstructed airflow.
