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.
