THis would actually be your best/cheapest solution on the interim. You
short Pin 14 to GND on the ATX Power Supply Connector. this allows it to
power on automatically. If you want to get more sophisticated, you can then
wire in a switch, or take some perfboard, order an ATX Female connector,
some DIP Molex Board connectors, and wire it up with any number of outputs.
It's how I've been powering my MEB, externally SATA HDD, and misc devices.
