61 LED's requiring about 3.5 volts a piece wired to an ATX power supply... I could hook them all up in pairs on the 5 volt but that's not enough voltage to light up the really bright ones, or I could hook them all up to the 12 volt and watch them pop because I am sick of looking at them all.

What would be a good resistor to use with the 12 volt rail, leds in pairs? or any other suggestions?

Hook up 4 in a row to the 12V line.
