For the enclosure, I was planning on having cut 1x6s along the edges of the panel. I would like the entire thing to be made of wood, as it is durable and can easily be spray painted. It will probably be mostly black but I may change my mind depending on how it looks with the components installed. For the backing, I am planning on having an acrylic or plastic transparent sheet that will be magnetically attached to the back of the box.
