This simple guide will show you how to make a switch bay from a 3.5" floppy blank. Since many modded cases have more than one light source either inside of or outside the case a front mounted switch bay can make turning them on or off easier by putting your switches onto the front of your case and within reach.

"For something that is so easy to make it looks damn good. We have seen this same thing for sale at a mod store for $10 but they only have 2 switches, so ours is one better."
