Aluminum Case for Pi 3 B/B+

The Micro Connectors RAS-03RDPWR-PI is an aluminum enclosure built for Raspberry Pi 1 Model B+, Pi 2 Model B, and Pi 3 Model B/B+ boards. It includes a UL-approved 5V/2.5A micro-USB power adapter with an integrated on/off switch. The precision-cut chassis provides clear access to every port while the metal body acts as a heatsink. Supplied thermal pads and anti-slip feet complete the kit for desktop or wall mounting.

Upgrade from Plastic Shells

Makers moving from basic plastic cases gain passive cooling through the aluminum body and the included heat-sink kits, which help sustain performance under load. The bundled power adapter adds a physical on/off switch and DoE Level VI efficiency, removing the need to hunt for a separate 2.5A supply. The jump is worth it when a project runs continuously or sits in a warm enclosure where thermal throttling becomes an issue.

Makers Needing Integrated Power and Cooling

This bundle suits hobbyists and IoT builders who want a single package that protects the board, manages heat, and supplies reliable power with a convenient switch. It is not for users whose boards require USB-C power, builders who need HAT clearance beyond the standard profile, or anyone deploying a Pi 4 or later model that uses a different form factor.
