Just a little tip that might help some people out. It seems that if you have a cold cathrode light with a round rocker switch (like the kind from PC Toys), and an Antec P160 case (or something similar with the same interior) you don't have to necessarily mod your case. The round holes in the 5 1/4" bays are a perfect match for the round rocker switch. You just have to shave a little bit of the side of the rocker switch to make it work. Otherwise it's a perfect fit. Obviously, you have to take off the side panel to get to the switch, but if you never turn the light on or off using the switch, then you don't have to worry about it. It just keeps the switch from floating around inside your case (and it doesn't look to shabby with a windowed side panel either.) This keeps you from having to cut a hole in your case to mount the switch.
Hope this helps some people.
