I've been trying, unsuccesfully to get my motherboard to boot up on keyboard input (put up a few threads for help and have gotten a handful of answers, but no solutions yet).
Anyhow, I'd like to be able to have a single button for turning my cabinet on and off. If I had a button that would both short the motherboard's power pins, as well as cause an ipac input, power on and off would work great (pin shorting turns on PC, ipac input causes default mamewah exit action (shutdown)). Holding button for more than 4 seconds causes a power off should something go wrong.
But, since I'm an idiot at this (and a lot of other) stuff, I want to make sure that I'm not going to damage my ipac or motherboard by sending the NO line to both, or just chaining the two together.
Tips/Suggestions/Cautions etc.?

im not really sure what you mean about connecting to an ipac.
Tonight whilst setting my mobo up for my cab, i tested using a arcade pushbutton to turn the pc on. took me a few attempts, but got it working...

No, you can't wire both your PC power pins and your IPAC pins to a single microswitch. It would burn something out. Besides, even if it did work, every time you hit that button something bad would happen - if you're in Dos, the computer would shut down. If you're in windows, it would kick you out of Mame and pop up the "Shut Down Computer" dialog box, or put the computer into sleep mode, or do something else, depending on how windows is set up.
You can have a pushbutton dedicated to the power-on pins on the motherboard though. (just can't put it in parallel with the ipac.)
Have you looked in your Bios, to see if there is a power-management feature for turning the computer on when a keyboard key is pressed? It might be something as simple as that setting not being set right, or it might need the Ipac to be plugged to the PS2 port instead of USB.
