a whole mat that you can set the entire case onto would be a good investment. when you hook up the bracelet to the chassis of your computer, remember to move it back and forth to scrape the paint off a little so you get down to bare metal, since most computer chassis are painted...it looks like bare metal but usually is painted gray.
