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? |

(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. |
