I was just wondering if anyone every used a good 'ol Happ push button to turn on their arcade. The cherry switch is rated for it I do believe. Just wanted to hear the experts thoughts on the matter...Thanks

A regular happs PB is momentary so you have to connect the PB to something that will turn on your cab such as your PC and a relay.  The momentary contact on a regular PB only supplies power when it is pressed.

My plan for my MAME cabinet is this (though I haven't actually put it together yet).

The the motherboard power switch connection would be routed to a regular game button, probably located next to the original cabinet power switch.  (that switch would still be there, but would be used to cut power to the entire box).  In Windows control panel, tie the power switch to the 'hibernate' function.  Now, when the button is pushed, the computer hibernates, push it again and it turns back on.

For the rest of the cabinet's components, I have a solid-state relay that will be mounted to the inside of the cabinet.  The trigger side will be connected to the 5v leads from a stripped USB cable, which is then connected to the motherboard.

This is just my idea, putting together my experience with PCs and electronics.  Someone here with more arcade experience probably has some better ideas.

That's right Boba, I went to my local Sears and picked up the automatic power switch. I was thinking that I could get a red nova gem as my cab power button. One button turn on. Just was wondering if anyone else had tried a regular PB in this manner.

I'd suggest using the PS +5V source, rather than the USB +5V source.  The USB can be setup to provide +5V all the time (+5VSB), and while I'm not sure, some devices (like a U360) may want the always on +5V power (thus ruining your turn on plan).  Even if right now you don't think that you will be using +5VSB, you may want to in the future...
