The case manufacturing process is such:
1. Shear the blank to size.
2. Punch the holes.
3. Notch the corners. (you will notice that all the corners have a small punched hole at the apex of the notch)
4. Bend to shape.
5 Clean and anodize the part. (getting the same gold color every time is difficult since the depth of color depends primarily on the immersion time in the dye)
6. Silk screen the graphics.
