Any good tips for cleaning up the case on a Dreamcast? Mine has mild yellowing and a few bits of filth on it, but I don't want to destroy it by accident!

A damp cloth and some elbow grease should sort out the filth but the yellowing is usually due to a chemical reaction on the casing itself but the above website shows how to get your retro gear back to pristine condition.
