Product information

Description

The Cooler Master TD300 Mini Tower Black is a compact PC case combining a three-dimensional polygonal mesh front with practical cooling features. The mesh front panel diffuses illumination from the included SickleFlow PWM ARGB fans and provides a balance of airflow, dust filtration and structural strength. The case supports Mini-ITX and Micro ATX motherboards, a bottom-mounted ATX power supply, tempered glass side panel, and multiple options for fan and radiator installation to fit small yet upgradeable builds.

Advantages

The polygonal FineMesh front uses a three-dimensional contour to increase airflow while reducing dust intake. Two pre-installed 120 mm SickleFlow PWM ARGB fans and the included ARGB/PWM hub simplify lighting and fan control and reduce motherboard header usage. A removable top panel and an adaptable drive cage make assembly and cooling installation easier. Tempered glass side panel offers a clear view of internal components and custom cooling, and the compact dimensions still allow for sizable components like a 344 mm GPU or 166 mm CPU cooler where applicable.

Suitable for

  • Compact gaming or productivity builds using Mini-ITX or Micro ATX motherboards
  • Systems requiring good airflow and ARGB lighting in a small footprint
  • Builders who want an easy-to-assemble case with visible components through tempered glass

Key specifications

  • Model: Cooler Master TD300 Mini Tower Black (MPN TD300-KGNN-S00, EAN 4719512124154)
  • Form factor: Mini Tower; compatible with Mini-ITX and Micro ATX
  • Dimensions (W×D×H): 210 mm × 366.5 mm × 210 mm
  • Material: Steel, Plastic, Mesh; Color: Black
  • Included cooling: 2 × 120 mm SickleFlow PWM ARGB fans and ARGB/PWM hub (5 ARGB + 4 PWM ports)
  • Drive bays: 2 × 3.5" and 4 × 2.5"
  • Expansion and clearance: supports up to 344 mm GPU length, 166 mm CPU cooler height, up to 325 mm PSU length
  • Front I/O: 2 × USB 3.2 Gen 1 Type-A
  • Weight: 5.85 kg

How to use

Install a Mini-ITX or Micro ATX motherboard and secure the bottom-mounted ATX power supply in place. Route the ARGB and PWM cables from the pre-installed SickleFlow fans to the included hub, connect the hub to the motherboard for power and control, and arrange additional fans or radiators as needed—front, top and rear positions are supported. Slide or remove the adaptable drive cage to create additional space for a longer PSU or larger radiators, then close the tempered glass side panel to view the assembled system.

Usage recommendations

For best thermal performance in compact builds, use the polygonal FineMesh front with at least two intake fans and ensure proper cable management to maintain unobstructed airflow. If you plan to install a large GPU or multiple radiators, adjust or remove the drive cage to free internal space. Use the ARGB/PWM hub to centralize fan and lighting control and minimize the number of motherboard headers required.
