My In-Win Mana 134 case provided me three standoff pieces for my mobo (MSI H61M-P23 B23). Several bleeding fingers and a couple hours later, I'm thinking that it's literally impossible for the mobo to fit through the io shield with the standoffs. There are four standoff holes on the mobo and the case, and three physical standoffs, so obviously, there has to be a configuration where one of the holes is not going to be used. I just don't know which hole gets skipped. The one closest to the io shield? The one on the top? Bottom? I've kinda jammed it in the io shield right now, but it's not the proper flush way that it should be. I think it's also preventing me from putting an Asus 5450 in the PCIe slot because the metal piece of the card where it will eventually be flush with the case so I can screw it down seems to be just a few mm too long so I can't push down the card properly. Any tips?
