Step 3: Installing the CCFLs & invertors in your case.
Here you are free to do what you want. Mount your invertors where you like, just make sure they don't make contact with your case (I used some foam to place them on). U can do that by using the carton boxes where your invertors were packed in when you bought them.
The only thing you should make sure of is that you don't make your wires from your inverter to your CCFLs too long. (you can make the wires from your molex to your inverter as long as you want) Like I said before, this gives reduced light.
Step 4: Connect your invertors to your baybus.
This is the final step. Once your invertors and CCFLs are installed, you can connect them to your switches. After that, you can drill the holes in your free 3,5 or 5,25 inch plate. Make sure you don't make your holes too big. For your switches, that's not much of a problem, because the margin is big enough and you can tighten them with screws. For your LEDs, make sure the hole is rather too small than too big. If you don't want to take the risk, you can buy LEDholders in your local electronics store.
Now take a deep breath, start your computer and lighten up your CCFLs.. Amazing
There you go.. That wasn't that hard was it? I hope you had fun reading this small how-to, I had fun making it, so don't worry about that :)
