Steel case for HiFiBerry Amp2 and Pi 4

This is HiFiBerry's most robust case, made completely from steel. It is ideal for environments that need something rugged or for people that don’t like plastic. You can add a 25mm fan on the side. As most users prefer a quiet system without a fan (which is totally fine!), the case doesn’t include a fan. Any standard 25x25mm fan should fit.
