Hi all. I have an Antec 1200 case and a ASUS M4A79T Deluxe motherboard now I just fitted the motherboard and ahve began to fit hardwrae into the PCI-E slots. However, this is not possible as the PCi-E slots do not line with the area at the back for the interface to go into. Can anyone help me? I really don't want to return the case or the motherboard but I fear I may have to.
