Whenever you install a new expansion card into your desktop computer, you get to remove a little piece of metal that once served as a placeholder. You can save this if you ever need it again, throw it away, or do what redditor jorshrod did: turn it into a coat hanger.
You might be wondering how this little piece of metal becomes a coat hanger. You simply bend it so it fits over the top of any door or cabinet and suddenly it's a hook to hang your coat. Pretty clever!
