I have an x -q-pack with a nec in it.
I need to replace my psu too. Any standard psu being 5.5 deep will fit. I fit a skyhawk in it but it suxed so
i took it out. They are all gonna be tight and you more than likly wont be able to use your bottom 5 1/2 bay
becuase of where the wires come out on the powersupplies hope i helped.
