The Tower 300 Hydrangea Blue is a Micro-ATX vertical chassis in an octagonal prism shape designed to offer high hardware compatibility in a compact footprint. It supports up to a 420mm AIO radiator on the right side, fits standard PSUs up to 220mm, and can accommodate GPUs up to 400mm (without power cover). The case includes three 3mm tempered glass panels on the front, perforated side panels, pre-installed CT140 white fans, dust filters, and top I/O with a USB 3.2 Gen 2 Type-C and two USB 3.0 ports.

Advantages

The Tower 300 Hydrangea Blue combines a classic vertical body design with an octagonal prism form to reduce footprint while maintaining airflow. It supports large radiators and multiple fan configurations (up to eight 120/140mm fans) and ships with two CT140 140mm PWM fans pre-installed for immediate cooling performance. Removable tool-free panels and a dismantlable modular design simplify installation and maintenance. Optional accessories such as the 3.9" LCD Screen Kit and Chassis Stand Kit enable horizontal placement and real-time display customization.

How to use

Install the motherboard (Mini-ITX or Micro-ATX), power supply (up to 220mm) and storage drives according to the included mounting points. Use the removable fan bracket on the right side to mount either three 120/140mm fans or a 420mm/360mm AIO radiator; the bracket is removable to simplify installation. Connect pre-installed CT140 fans to the motherboard or fan controller and route cables through the modular openings. For horizontal placement, install the separately sold Chassis Stand Kit: remove the original feet, attach the new bottom cover, and place the chassis onto the stand. When installing an AIO, position the radiator higher than the pump where possible.

Recommendations

For optimal cooling, configure intake and exhaust airflow using the top and side fan positions, keep radiators higher than AIO pumps, and use provided dust filters to reduce maintenance. If you plan to show system information or custom images, use the optional 3.9" LCD Screen Kit with TT RGB Plus 2.0 software.
