I dont know if you had me in mind or not ben, but the bracket i was talking about is not the mounting plate. Its a support bracket for the PSU, it mounts right under the PSU on the SX1240 case.
take a peek here if you want to know what i mean...

the second hole on the cross bar is where it screws in, and since i have a WTX PSU it dips, and is bending the bracket you posted a link to.
and to make it better, antec told me they cant get me the bracket no matter what i do, I have to buy another case if i want it. lol
