If you want to get wicked DIY on the fans, you could adapt a power supply from a computer to run them. It helps to use a PS with a switch or to wire it into a switch because the fan will be hard wired.

To rig up a power supply so that it can be on without a motherboard you need only to find the green wire in the 20/24 set of wires that usually plugs into the motherboard and connect it with any of the black wires. Then connect the red and one of the black wires of any of the 4 pin molex connectors and you're good to go.

If you want to get fancy you can open up the PS and cut all the wires apart from the ones in use real short and then close it back up. Makes for a cleaner look.
