Dont ATX PSUs require some kind of remote turn on switch similar to a car amplifier kind of thing?

I mean simply supplying power to an ATX PSU wouldnt be enough would it?

Quick answer, bridge pin 14 to GND.

No, you just jumper two of the pins (search around here, there's lots of talk about it) which keeps it on.  (edit: I see that's been done for you!)

However I prefer the K.I.S.S. method, and usually use good old fashioned AT PSUs. Flip a switch, and it's on. Done. Cheap too if you have to by new. Less than $20 on Newegg

But don't discount wall warts you have laying around. LEDs and fans don't require much in the way of amperage.  In my cocktail, I run all the LEDs off a 5V wall wart, and two cooling fans and some other goodies of a 12V. Hey, they were free. For my upright I used an AT PSU, partially b/c my coin door lights are 12V lamps and not LEDs and so needed some extra oomph.
