Product information

Description

The Tower 300 is an m-ATX chassis with a classic vertical form factor presented in an octagonal prism shape. It supports up to a 420mm AIO radiator on the right side, accommodates long GPUs (up to 400mm without power cover) and standard PSUs up to 220mm, and comes with two pre-installed 140mm PWM fans on the top. The case offers tool-free tempered glass and perforated panels, multiple dust filters, and optional upgrades such as a 3.9" LCD Screen Kit and a Chassis Stand Kit for horizontal placement.

Advantages

The Tower 300 combines compact vertical styling with high hardware compatibility, allowing installation of high-end components including large GPUs and a 420mm radiator. Tool-free panels and a dismantlable modular design simplify assembly and maintenance. Pre-installed CT140 fans, extensive airflow paths and multiple dust filters provide effective cooling and clean operation. Optional accessories (LCD screen and stand) enable visual customization and alternate horizontal placement.

Key specifications

  • Form factor: m-ATX chassis in octagonal prism design
  • GPU clearance: up to 400mm (without power cover)
  • CPU cooler height: up to 210mm
  • Power supply length: up to 220mm
  • Radiator support (right side): up to 420mm / also supports 360mm
  • Fan support: up to eight 120mm/140mm fans; two 140mm fans pre-installed (top)
  • Storage support: up to three 2.5" SSDs or three 3.5" HDDs total
  • Front/top I/O: 1× USB 3.2 Gen 2 Type-C, 2× USB 3.0
  • Panels: three 3mm tempered glass front panels and two perforated side panels; tool-free removal
  • Filters: top, rear, inner sides and inner bottom layer dust filters

How to use

Install components following standard PC assembly procedures, using the dismantlable modular design to access interior mounting points. Mount the power supply, position the motherboard and route cables through available channels, then install storage devices in the designated brackets. For right-side cooling, fit either up to three 120/140mm fans or a 420mm/360mm AIO radiator onto the removable right-side fan bracket, ensuring the radiator is positioned higher than the AIO pump. Panels and tempered glass sections are removable without tools for easier installation and maintenance.

Recommendations

Position radiators higher than the AIO pump when using the right-side 420mm/360mm installation to avoid air pockets. Use the included dust filters and clean them regularly. Consider the optional Chassis Stand Kit for horizontal placement or the 3.9" LCD Screen Kit for real-time monitoring and visual customization.
