One of the funnest things to do is mod your case to look stylish, cool, unique or eye-gouging. This thread here has a collage of photos from PDXLan 5, a large-scale LAN party for the Western U.S., where a lot of people showed off their chassis. I admit, some of the designs are getting a little tired. Neon lights and clear-this-or-that are nothing to be impressed by anymore and often look tacky. Some of the cases pictured though are really interesting, such as the 'Nintendo' box (there is a guide online on how to make one), the one built inside a cylinder and a few of the “Themed” cases that have pretty decent artwork on them. Any case modder will find this interesting.
