You could make a simple LM317 based controller.
Like this one...

Here is a pic of the fan controller I made. It doesnt connect to the ATX power supply though. Rather it is connected to a 12.6v transformer rated for 3 amps. My controller has to deal with A/C power from the transformer whereas the one linked above doesn't.
Right now this controller is running three 120mm fans (sorry I cannot remember the exact power draw for each). I do know that the fans are rated around 100 CFM each @ 12v.
(this pic I somewhat old as I have changed the heatsink on the LM317 to something bigger)
