Use brass screws and hinges, amazing what a stray bit of static can do. Make sure it's vented as well. A sealed box can become a wonderful projectile(s). Stay away from electrical at least 1 meter, for everything, I believe that's the standard for code in Canada. Check out the stickies in this forum and read up on the explosives act, and check your local reg's as well.
