Product information

Description

The Tower 300 is an m-ATX computer case with a vertical octagonal-prism design that supports high-end hardware and flexible cooling options. It accepts a 4090-class GPU up to 400mm (without power cover), a standard power supply up to 220mm, and up to three 2.5" SSDs or three 3.5" HDDs. The chassis supports up to a 420mm AIO radiator mounted on the right side and can house up to eight 120mm/140mm fans in total. Tool-free tempered glass and perforated panels provide easy access, and pre-installed CT140 fans improve out-of-the-box airflow. Optional accessories include a 3.9" LCD Screen Kit for real-time monitoring and a Chassis Stand Kit for horizontal placement.

Advantages

The Tower 300 combines a compact vertical footprint with wide hardware compatibility, allowing large GPUs, long power supplies, and multiple storage drives. It offers extensive cooling versatility with support for a 420mm radiator on the right side, removable fan brackets, and space for up to eight fans. Tool-free glass and perforated panels simplify installation and maintenance, while pre-installed CT140 PWM fans and multiple dust filters help maintain low internal temperatures. Optional LCD and stand kits provide customization for monitoring and alternate horizontal display.

Key specifications

  • Form factor: m-ATX chassis with octagonal-prism vertical design
  • GPU support: up to 400mm length (without power cover); compatible with 4090-class cards
  • CPU cooler height: up to 210mm
  • PSU length: up to 220mm (standard size)
  • Radiator support (right side): up to 420mm (also supports 360mm)
  • Fan support: up to eight 120mm/140mm fans; two 140mm CT140 PWM fans pre-installed on top
  • Storage: up to three 2.5" SSDs or three 3.5" HDDs
  • Panels: three 3mm tempered glass front panels and two perforated side panels; tool-free removal
  • I/O ports: 1× USB 3.2 Gen 2 Type-C and 2× USB 3.0 on top panel
  • Additional features: removable fan bracket, multiple dust filters, Dismantlable Modular Design (DMD)

How to use

Install components as in a standard m-ATX build: mount the motherboard, install the power supply (up to 220mm), fit the GPU, and connect storage drives in available bays. For right-side cooling, choose either three 120/140mm fans or a 420mm/360mm AIO radiator using the removable fan bracket to simplify installation. If using the Chassis Stand Kit for horizontal placement, unscrew the original feet, install the new bottom cover included with the kit, then carefully place the Tower 300 onto the stand. When installing an AIO, position the radiator higher than the pump to help avoid air pockets.

Recommendations

For best thermal results, keep at least two intake/exhaust fans in your configuration and use the pre-installed CT140s on top. Install dust filters on all intake locations and, if you plan horizontal placement with a radiator, ensure the radiator sits above the AIO pump. Consider adding the 3.9" LCD Screen Kit for real-time monitoring if you want on-case system information.
