Using this Bel-Aire case is easy. Just place your Raspberry Pi 2 or Model B+ (or compatible models) inside the enclosure. Make sure all the ports are properly aligned for easy access. When using, keep in mind that this case is only for specific Raspberry Pi models as mentioned. Do not try to fit other non-compatible models. To maintain it, you can use a soft, dry cloth to wipe off any dust or debris. Avoid using harsh chemicals or abrasive materials that could damage the laser-cut birch finish or the graphics. And always remember, you need to provide your own Raspberry Pi as it's not included with the case.
