Xtrex, that is pretty nice! Maybe you will put the cathodes right behind a solid piece of the case. This way you don't see the actual cathode but you still see the lighting effects. Can't wait to see the final product and the mod guide on how you did it. Are you planning on submitting for the mod challenge?
