Raspberry Pi 4B Metal Case with Dual Fan

This carefully polished aluminum alloy case is designed for Raspberry PI 4 B—light, strong, with excellent thermal conductivity and corrosion resistance to protect the motherboard. Its anodized surface enhances texture. It retains all peripherals (camera, GPIO, mouse, keyboard, display) and has bottom screw holes for wall mounting. Compared to PI3, PI4 has less heat dissipation and smaller size; avoid heatsinks for the network card (risk of short circuit). The high-speed USB3.0 chip (near CPU/memory, high heat) needs an overall heatsink.
