What You Need
	Case & Mobo that supports Intrusion Detection
	SPDT Roller Lever Switch (Radio Shack 275-017A)
	2 - 2mm Screws
	LED w/ Cable or compatible
	Tools, (Soldering Iron, Heatshrink Tubing, Etc.)

I am not responsible if you screw up your own gear, use logic and if you don't know how to solder, please learn.

The case I will be using for this one is a Chenming 601AE which has the option for an intrusion switch
The motherboard is a ASUS A7N8X-E Deluxe and supports chassis intrusion detection even if it is minimal alerting.

Now granted I thought about writing this after I was done so not all the pictures I would normally want are here but you get the idea.
First off get everything you need together....

Creating the switch

Take the LED cable and cut the led off and strip the wires and then solder the wires to connections 1 and 2 on the roller lever switch
it doesn't matter which wire goes to which connection on the motherboard because it's just completing the circuit to tell the motherboard that the case is in fact closed, the circuit breaks when the switch is depressed and lets the motherboard know that the door is open.

Installing

Now that we have the switch completed it's time to install. You may need your motherboard manual for this part.
Open up the case and locate the designated area for the switch to be installed,

This is what the mount area looks like on the chenming 601AE it uses 2mm screws.

I had a bit of trouble getting screws luckily my hobby shop had some 2mm x12's and I was able to lop off a little bit because they were too long. Even though they were the most expensive screws I've ever bought. $1.60 for 4 downside they use an allen wrench. For the record they are DU-BRO Cat No. 2114

Screw it down.

All thats left now is to connect it to your motherboard, consult your manual for which jumper this is.
On the ASUS I am using it's right between the SATA and the groups of jumpers for LEDs, and Switches, remove the installed jumper and slide the new connection on. Then power on with the door off, it should say WARNING! CASE OPEN! or something similar. Lame I know, but it's a feature and I wanted to use it because it was there. I had contacted ASUS about sofware in windows that would say notify me via email when the chassis gets opened but they only offer it on boards that support ASMS or something and those are the enterprise grade server boards and not mine.

If ASUS is reading this, seriously add the funcionatly to the ASUS monitoring software I'm sure it would be easy, hell MSI offers it, or even allow it to be probed by Motherboard Monitor.
