So I have a question:
I assume this allows you to mount an external switch on the cabinet and with a flick you can power up an ATX board instead of reaching inside and pushing the button every time you power it down.  Where does the switch tie into?  I'm having a hard time figuring out how the hard drive power connector fits into this.

Thanks!

I disconnected the power button that goes from my PC case to the motherboard.  I then rewired it so that a pushbutton from the control panel connects to the "power" connector on the motherboard.  All this does is move the pushbutton from the PC case to the cabinet's control panel.  The PC's power supply is plugged into the "always on" outlet while the monitor, marquee light and speakers plug into a power strip which plugs into the "relay switched" outlet.

The hard drive power connector coming from the junction box needs to connect to a spare hard drive connector inside the PC.  When the PC turns on the 12V from the PC's hard drive connector turns on the relay which turns on the "switched" outlet.

Does this make sense?  Let me know if you have any other questions.

Thanks,
COBeav

Hey COBeav, great write-up!  I was looking for a good single power switch solution and this is by far the best idea I have seen and I will certainly use it in my cabinet.  Thank you for taking the time to share your idea!

Can this be done without soldering?

Thanks

I wouldn't do it without soldering mainly because I wouldn't want anything to come loose and create a short circuit at these voltages.  You might be able to crimp the terminal rings onto the wire.  Also, it might be possible to crimp the female side of a spade connector onto the wire which then slides over the terminals of the relay, but I don't know if the relay terminals are a standard size to create a snug connection.
