There exists port covers for nearly any kind of connector port, though obviously the less proprietary, the cheaper and more common they will be, like say, USB, HDMI, and VGA port covers. I use USB port covers with my PS3 and PS2. Little black silicone plugs with a small tab for removal. Pretty handy. I should get more, as I have a metric buttload of computers and consoles that collect dust and aren't on "display".
