ok, it used to exist on their site :S though that was a long while back that I last visited the page
ok, no worries, thanks for your help. any ideas anyone else ?
Easy enough to implement but finding the key part is the hard part. The ones I see are ~$20 -$40. Basically your looking for a lawntractor/boat key with off-run-start positions.
After cutting the front panel; power switch wires (you'll need the ones that go down to the motherboard) You wire the 'hot' or 12v feed to the motherboard front panel pwr sw- and the 'Start' to pwr sw+, and leave the 'run' disconnected. Your motherboard only uses a momentary contact like 'start' to turn on so thats how you'll turn on your pc. :-) just like starting a car except to turn it off by the key you'll need to turn it to 'start' again. You'll nbe able to turn it to 'off' at anytime and remove the key even if running but anyone will be able to click start>shutdown. No one will be able to turn it on without the key unless they open the case and jumper the switch.
I wouold check my local boating/lawntractor stores and repair centers. They probably have a few instock. I even found some at the golf cart store. Golf carts are like lawn tractors and take a generic key so if you dont want anyone to just take yours you have to replace the stock one ...
