Can a switch replace my computer's power button?

thats what i did..wired my POWER and RESEST leads from motherboard to arcade buttons.  works fine for me.  i would imagine any MOMENTARY , not OFF/ON  would would.  as this is what is in most cases.  push and turns on...hold (keeps contact) powers off/hibernate ect.)

Currently you turn power on/off using a momentry switch connected to the motherboard (MB).  You can do exactly the same for an always-on switch by connecting onto the ATX->MB power supply connector instead.

if you have an ATX+ style power supply, then one of the pins where the ATX connector goes to the MB is a "Power Supply On" (PSON) trigger.  This works the way you want it to - it will keep the PC on as long as the switch is closed.  If the switch is opened, the PC goes off.  Only 5v runs thru the signal line, so it is quite safe.

For ATX 20-pin connector to MB, PSON at pin 14, ground to pin 15

For ATX 24-pin connector to MB, PSON at pin 16, ground to pin 17

The easiest way to test this is by exposing/twisting your wire ends, and inserting it into the back of the ATX->MB connectors so as to make good & secure contact.  Once you test it and are sure that you have the right pins, you can solder the wires to make sure.

Simply install a power strip in the cab,  then extend the power switch from the strip and mount it (or another switch) to your cab.  Set your BIOS to boot after power outage and you are good as gold.  That is how i have 2 of my MAME cabinets set up.

I mount the power strip right inside the coin door on my cabinets.

Just open the door, reach inside, flip the switch and the monitor/marquee light/speakers power up, while I'm in there push the PC power switch and get ready for some Joust!

It may not the greatest solution, but it is simple and even the most un-tech savvy (IE me) person can figure out how to set it up....
