Thanks for your response. But my mistake, I was talking about the rear I/O Shield that comes with the motherboard. The Core P5 Case does not come with a bracket to attach this shield. I was hoping that someone could 3d design one, that I can print and use. Since drilling holes in the case will void my warranty, a non drilling option would be appreciated (if possible). If drilling is the only option, to hold the bracket in place, then that's fine to.
