Be sure to wear goggles or something to protect your eyes. A whole face
shield might be infinitely better. Also gloves of some sort on your
hands. Even with hand snips, if a little bit of shrapnel flies into your
eyeball that may permanently end your embedded engineering feats. The
same applies to hands or fingers sliced by metal.

With that said, cut a sufficient circle in the computer case and debur
it with a file or rasp so it doesn't slice your hand. Then hot glue the
D-sub bracket to it. If the glue has poor adhesion to the metal of the
case, solder the bracket on. Presto! It's quick and it works.
