First time making an enclosure. My AP cases were bought built. But I know how to use a speed square to make a quick box. There’s a little finish and trim carpentry goes on here. The process of building the box (4 sides+2 back panels) is a project anyone can do successfully. Most probably under an hour. With a square, corner clamp, drill bit, countersink bit, and screws.
Just a little understanding of the butt-joint will go along way in anyone making their own custom size. Eventually I may lay this out in instructional format. Took some pictures of the steps. 🤷
