thanks, that is a great suggestion and i will definately look into it, but first i would like to investigate the possible use of an ibutton as the power button, basicly i am planning on chopping up one of the door locks that outputs 12v when it detects the right ibutton, i just gotta figure out a way to make this turn the computer on, but i know it can be done.
for any of you that are interested (probly none) i have come up with the 'perfect' secure game server for lan parties. The case is secured with screw locks (easy to come by) to prevent the case from being opened. For a nic it runs on a wi-fi adaptor completely contained in the case to prevent tampering. A usp (uninteruptable power supply) is built inside the case and the powersupply is run through it so that you cannot unplug the psu only the ups from the wall. Keyboard video and mouse are handled by the above mentioned interface, the hacked up door lock i mentioned in this post will be used for power button. As the final (and really not nessissary) point of security is a program that refuses to accept keyboard and mouse input and locks the computer at a screensaver unless an ibutton is currently interfaced with the computer.
I know this is massivly overkill but i am going to submit it to a small design challange run by some local lan party host and i think this system will beat anything else there in the catagory of preventing unauthorized access to the game server.
