Seeking advice for MAME cabinet replacement or Multi-pac

[TurboC--]

Overview - long ago I restored an original Pac-Man cabinet and set it up with AdvanceMAME.  It runs an authentic replacement arcade monitor, with an iPac and a crappy Compaq Celeron 400 that happened to be able to output arcade monitor frequencies, and was good enough to run the early 80's classics.  Years later I sold it, but I still do the maintenance.  Now the Compaq's power supply has (apparently) died.  Here are my options:

- Replace the Compaq's power supply - it used a proprietary AT 110W (lol) supply, replacements for that are way overpriced.  I don't like this option since it's throwing too much money at a garbage old machine.
- Find a cheap used PC to throw in there which would act as a better, cheap replacement
- Put in the original Pac-Man PCB I, in fact, actually own for this purpose

The owner of the machine doesn't want to switch to a Pac-Man PCB because he likes a larger variety of games.  There is a 96-in-1 multipac chip but it's $95, plus it's currently out of stock, so he doesn't want to do this option.

If I look for a used replacement PC, I will be looking for cheap machines on craigslist and such, but I have the following 2 issues:

1.) I won't know in advance if the replacement PC's video card will support arcade monitor frequencies before purchasing it,
2.) The existing dead Compaq's case had the great advantage of staying in a "power-on" state.  This way all the guy had to do was plug the whole machine in, and not have to touch anything inside.  I would want any replacement PC to have this ability for its case to always be powered on, but I don't have experience on knowing how or when this is possible for a given case / mobo.

I would appreciate either advice for what sort of old PC I should be looking for which would likely serve as a replacement (remember it really doesn't have to be powerful, I was running AdvMAME on a Celeron 400 for god's sake so even as old as a P2 class might work).  Or, if anyone has a line on a Multi-Pac chip or knows of some option similar to multi-pac which I could install on my Pac-man board, that might work too.  Thanks!

Mike doesn't seem to be making any more at least not for a while now. If you're handy with a soldering iron and can but roms you can do the Souza 4 in 1 hack. You could also get a pac can to jamma adapter and put a 60-in-1 pcb in it.

I just found out that the multipac chip isn't as good as I thought - for one thing, super pac man isn't really super pac man, it's an adaptation version for the Pac-man PCB.  That doesn't really thrill me.  The following questions then:

1.) Can you link me to a list of video cards or test program that would let me know what cards would output arcade monitor frequencies?
2.) Is there a list of good cheap video card options for PCI / AGP / PCI-E or whatever graphics card slot I might find myself with?  I remember one was recommended as a cheap reliable video card for arcade frequencies but that was so long ago. 
3.) Is there a way to rig power buttons (presumably in a standard ATX case depending what I find) to be always on?
