Not exactly sure what you mean?

Here are my thoughts...

1) you just need to figure out which two wires that connect to the control panel pins have your power on signal.  Its a +5v signal.  you short that with a ground and if the whole thing fires up you have found it.  I don't know if randomly shorting these pins for a moment would hurt your computer.I imagine those pins go to the power button, the HD LED, the Power LED and probably the Speaker. The two wires you want to short are a 5v and a gorund that are right next to each other.  I don't think it would hurt anything,  and heck if you are just going to ditch the whole thing anyway, then i think its worth a shot.

2) if you boot into your bios, there may be a wake-on-lan option.  I was thinking about doing this for my cab.  If your cab is hard wired into your lan, you can remotely boot up the computer from another computer.  If you google "wake-on-lan" you can find a discussion about it.  I was thinking about setting my computer to wake on LAN, and then using an iphone app to turn the whole thing on from my phone.  I was going to plug my computer into a smart strip, and then I would be able to turn everything on from my phone.  I thought that would be cool. I didn't go through with it because I couldn't figure out how to make the cab sleep on LAN, and I didn't want to keep it on all the time, or shutdown my computer from my front end because I didn't want people messing with the front end accidently shut down the cab.  But if those aren't concerns of yours, its an option.

Put it all together, but leave the case open. Unplug a header, plug in power, and push the power button. If the computer still turns on, then you got the wrong header so repeat. If it doesn't, then you've got the right header.

Once you've found the right header, turn off the computer, and grab a small flat head screwdriver and just start jumpering pins, until your computer turns on. The pins only need to be jumpered for a second to initiate the process. Narrow it down to a couple pins and use those two, wired to a push button to turn on your PC.

It sounds sketchy, but when a computer's turned off, you can't really do any harm to anything by jumpering the wrong pins, and if you turn it on, there's not really much voltage that can harm anything...

Personally, I just used my DMM and found the power button...

Much safer to check the unplugged ribbon cable with a VOM and see which wires have continuity when the power button is pushed.  That way nothing is shorted and everything will work afterwards.   Takes longer though.

Ok I have a dmm.  Could you please be mote specific on what I'm to do with it?  I understand what you are saying but don't understand terms like "jumpering" etc.  What do I set the dmm to?  Turn the pc on and start sticking the dmm's prongs in the holes and look for 5v?  I'm lost.
