The Akasa Pi-4 Pro is a high-quality aluminum case designed specifically for the Raspberry Pi 4 Model B. It not only provides robust protection, but also efficient passive cooling through an integrated thermal kit and heatsink top cover that effectively dissipates heat away from the processor, GPU and USB 3.0 chipset. This case is ideal for applications such as media players, retro gaming, DACs and other Raspberry Pi-based projects.
