  • 4 ARGB Fans Pre-Installed : Comes ready with 3 × 120mm ARGB front fans + 1 × 120mm ARGB rear fan, so airflow and lighting are handled straight out of the box.
  • Up To 11 System Fans : Fan mounting positions across the front, top, rear, side, and PSU shroud allow up to 11 × 120mm fans for serious high-airflow builds.
  • 360mm Top Radiator Support : Supports liquid coolers up to 360mm on top, plus up to 240mm in front and 120mm at the rear, giving builders flexible AIO placement.
  • 390mm GPU Clearance : Graphics cards up to 390mm long and 150mm high are supported, giving large modern GPUs plenty of room.
  • 160mm CPU Cooler Clearance : Air coolers up to 160mm high fit inside, keeping tower-cooler builds fully viable.

  • 4mm Tempered Glass Panel : A 4mm tempered-glass side window puts your GPU, cooler, motherboard, and ARGB setup fully on display while keeping the chassis visually clean.
