About this product

Desktop PC Case Unobstructed View D40 Dual-Chamber Panoramic Design A frameless panel design eliminates visual barriers, delivering a clean and open view. Seamless integration between the front and side panels ensures a perfect system display from any angle. The front and side tempered glass panels feature a ball-head push-pin mechanism, allowing quick and easy removal for maximum convenience. 8-Degree sloped bottom design to maximize airflow The 8-degree sloped bottom intake system optimizes incoming cold air by splitting it into two pathways. When the GPU cooler is idle, external air—which would otherwise stall beneath the GPU—is divided into two channels. One stream delivers fresh air directly to the graphics card, while the remaining airflow is guided around the GPU via the Coanda Effect before rising toward the CPU and VRM, creating a three-dimensional airflow path. Side Air Intake for Enhanced Airflow Optimized Side Airflow Design Perforated side intake supports fan and PSU ventilation, while the air vent enhances smooth and efficient cooling.
