Thermaltake The Tower 300 Micro-ATX Case with window, Hydrangea Blue

The Thermaltake Tower 300 is a Micro-ATX chassis defined by its octagonal prism shape and vertical orientation. Constructed from SPCC steel and three 3mm thick tempered glass panels, it offers a multi-angle view of the internal components. This design supports both Micro-ATX and Mini-ITX motherboards, providing a flexible foundation for compact builds. For additional placement versatility, an optional stand kit allows the chassis to be positioned horizontally, altering the system's aesthetic and desk footprint.

The chassis is engineered for substantial thermal management with support for both air and liquid cooling configurations. It accommodates up to a 420mm AIO radiator on its right side, a notable capacity for an enclosure of this size. The interior provides generous clearances, supporting CPU coolers up to 210 mm in height and standard PS2 power supplies up to 220 mm in length. Multiple removable dust filters are integrated to help maintain clean internal airflow and simplify routine system maintenance.
