I need to make several custom amp cases, just curious as to where anyone has found the most economical to source hardware, corners, latches and rail material from .. thanks!
I have never built a rack case, but I have used several from pearsoncases.com they offer a pretty wide variety of options. Might be cheaper then building if they have something that would fit your needs.
