OK, now I understand exactly what you're trying to do. My post above describes one solution.

: : Yeah, the power switch on an ATX mobo is a couple of pins that need to be "jumped" in order to power on. I don't know of a way to power it on when you flick a power switch on.

Like i said in the post above, you can just wire a Happs microswitch pushbutton with extension wires in place of the button on the computer case and mount the Happs button on your arcade cabinet. You would turn on your power strip, then push the Happs button to fire up the computer.

The more elegant solution would be to wire it up like I described in my previous post. By using a 12v relay wired to a power strip and wiring a Happs button in place of the power switch on the computer you can set it up so that when you push a single button your entire cabinet and computer will be powered-up. An added 'bonus' is that if you use Win95/98 and select shutdown not only will it turn off your computer but it will also power-down your speakers and monitor at the same time.

Don't waste your time jumpering the switch on the motherboard, it won't work. The power switch on the case is a 'momentary' switch...by jumpering the switch out you are effectively holding the powerswitch on the case in the "pressed" position. I don't think your computer would even boot up and if it did it would probably shut down again and/or be trapped in an endless boot-up shutdown cycle. When you hold down the 'on' button on my ATX mb/case for 4 seconds it will shutdown the computer.

: : HOWEVER, a lot of motherboards let you have an alternate power-on, such as mouse1, spacebar, esc. If you already have one of those as a button on your control panel, then you'd just have to hit that specific button to power the PC on.

:
: I have a switch on the back of my cabinet that powers on the power strip inside the cabinet. Right now the speakers, monitor and computer are all in the "ON" position and the power strip is left on as well. When I power on the cabinet, the strip powers up and everythign on it powers up. Problem is, like I said, that I have to turn on the computer via the power button on the front of the case.

: I'll try jumpering the power switch on the mobo and see if that works.
