I have two ST296Ns, they are fedd by a 65W power-supply.
Remember to shield the power-supply with metal and use thick enough
cables. Fan won't be bad either. I think you'll need something over
150W. Four drives at startup draw quite a large amount of amperes out
of the power. If you put some kind of a delay to power them up one at a
time, smaller power would be enough. 150W powers are quite expensive!
(150W +-12V, +-5V)
