I'm not sure why having a keyboard and mouse is a problem.
Every server environment I have come across has a keyboad and monitor attached so that any server maintenance and functions can be monitired and/or adjusted. They don't have to be swish items - just working! Rummage around in the 2nd user shops if need be. You can leave the monitor switched off when it's not in use.
So, do you have a real reason for wanting to leave these items out?
