For my Unreal Tournament 2007 case mod I'm going to be starting, I wanted to cut a custom window. After I cut out the shape and all I was going to add the plexiglass behind it like every other window. In my Lian-Li case, the window is held in with rivets, and I wanted to know how to do this by myself. I know you can buy rivets, but how do you install them? I hear that you need a rivet gun. If I do, about how much are they?
