ive got the motherboard in, and went to put the graphics cardin but the brackets at the back are quite persistent. The bracket behind the pci e slot, slanted grill type look. I can bend the top and bottom towards the middle of the bracket, and can bend it to the left as its on its side, i see no screws though. Is it a case of bending until it "snaps" off gently?
