Product details

The NZXT H2 Flow Midi Tower case is a well-thought-out solution for PC builders who value an optimal combination of airflow management and acoustic performance. With its innovative dual-chamber design, it separates the main component area from the power supply and cable management sections, which not only improves thermal regulation but also ensures a tidy and organized build. The front panel is equipped with a fine mesh filter that allows for efficient air circulation while maintaining a minimalist aesthetic. Three pre-installed 120mm fans are strategically positioned to ensure balanced airflow. The tempered glass side panel provides a clear view of the internal components while ensuring structural integrity. The case supports various motherboard formats and offers ample space for powerful cooling and storage solutions.

  • Dual-chamber design for optimal cable management and thermal regulation
  • Pre-installed 120mm fans for balanced airflow
  • Removable magnetic dust cover for efficient air intake
  • Tempered glass side panel for a clear view of internal components
  • Versatile storage options with vibration-dampening mounts.
