I'm in the process of basically installing the innards of my mac mini into a vintage cassette deck and use it as a htpc. My main question is what would be the best way to run the mac mini off a traditional ATX computer power supply? I could use the supplied power supply, but as this is a case mod, I'm also looking at adding additional components like a couple HDs and a DVD drive, so it's gonna need more power. Is it as simple as splitting some wires and splicing into the power supply? Or will I need some sort of power regulator between the PSU and the mini? My current mac mini is the older style setup. It was originally a 2006 1.66cd, but has since been upgraded to a 2.33c2d cpu.
