Aluminum Alloy Protective Enclosure for Raspberry Pi 4 with Cooling Fan

A bare Raspberry Pi board sitting exposed on a desk is genuinely vulnerable to scratches, dust, and accidental short circuits from stray metal contact underneath - this aluminum enclosure solves that while also addressing the Pi 4's real heat output, which throttles performance under sustained load without adequate cooling. Aluminum construction itself contributes passive heat dissipation beyond what the included fan alone provides, since the metal case body conducts heat away from the board more effectively than a plastic shell would.

Circular venting holes across the case aren't just cosmetic - they're specifically positioned to let the integrated fan actually move air through the enclosure rather than trapping heat inside a sealed metal box, which would otherwise make the case counterproductive. Precisely cut interfaces give clean access to every port (USB, HDMI, Ethernet, power, GPIO) without needing to remove the case for normal use.

Common uses are protecting a Raspberry Pi 4 in a permanent desktop or project installation, keeping the board cool during sustained high-CPU workloads like media serving or home automation hubs, and general dust and scratch protection for any Pi 4 build.
