Caja de PC Thermaltake Tower 300 Matcha Plum Micro Tower

The Tower 300 Matcha Plum is a Thermaltake micro tower PC case with an octagonal prism shape and a classic vertical body design. It supports Micro-ATX and Mini-ITX motherboards, accommodates a standard ATX power supply up to 220 mm, and fits long GPUs such as an RTX 4090. The case accepts up to eight 120 mm/140 mm fans and supports a 420 mm AIO radiator mounted on the right side. Three 3 mm tempered glass panels on the front and two perforated side panels are tool-free removable. Optional accessories include a 3.9" LCD Screen Kit and a Chassis Stand Kit for horizontal placement.

Advantages

The Tower 300 Matcha Plum combines compact vertical styling with broad hardware compatibility, allowing installation of high-end GPUs, a large AIO radiator and multiple fans while keeping a small footprint. Tool-free tempered glass and perforated panels simplify access and maintenance. Pre-installed dual 140 mm PWM fans provide baseline airflow, and optional LCD and stand kits enable monitoring and alternate horizontal display configurations.

Slide in storage drives into the provided 3.5" or 2.5" bays and route cables behind the motherboard tray. Reattach the tempered glass and perforated panels without tools for quick access.

Recommendations

For optimal cooling, combine the two pre-installed 140 mm top fans with additional right-side fans or a 420 mm radiator, maintain clear intake and exhaust paths through the perforated side panels, and use cable management to avoid airflow obstructions. Use the TT RGB Plus 2.0 software to personalize the optional LCD display and monitor system status.
