You could use a battery backup (UPS) instead of a power strip with this idea. Set the UPS software to shut down the machine immediately on power loss (and get rid of the annoying beeps). Then set the pc to restart after power loss.

You shut the PC down normal.

But if you want a completely hidden PC, i.e., no windows visible, that's a little hard...impossible, actually.

I mean shutdown from the frontend. I do it from Mamewah every day.
Once the PC is off, I flip the switch behind my cab to turn everything else off (a smart strip will eliminate this step).
Then to turn it back on, I flip the switch and everything, PC included, comes back on.

Yep. I've done it that way with one of my cabs for years and never had an issue. I've also done the switch-off without shutting down the pc for years on another cab without issue. Yet.

This is fine as far as data corruption goes, but I would be more concerned with the HD head crashing mid-write because the power is cut before it has a chance to park. This would (could) cause hardware failure.

I simply don't worry about that. So far so good, it's been 3-4 years. I've had drives die before that time that were babied.
How do "real" arcade games that have hard drives handle it?
I eventually plan to put a flash drive in there instead.

I have opened her up to wire (splice) the power on button to a push button for my arcade machine to power the computer on.
Low and behold, the power on button on the desktop is wired using a ribbon cable to this mini control panel (which has front usb and sound on it) which is then fed into the motherboard using another ribbon cable. :banghead:

I have a full-sized Dell with a similar design. I checked eBay and found somebody was selling replacement power switches for it. Basically the switch is on a tiny PCB, then there's a ribbon cable leading to the other small PCB that you referred to. So. . . I haven't hooked it up yet, but it should be easy to unplug the original ribbon and plug in the new one, and get access to the power signal through that.
I don't know if those power switches are still available, but it wouldn't hurt to do a search.

A mame cab should never be in a situation where it is writing anything of import to disk, thus they are usually pretty safe just to flip the switch on.
