i have standard atx board (msi z77 g45) and a standard atx case (ciT jupiter) and in the case, the top left 2 holes are different to the rest and dont allow a standoff to be screwed all the way in as the rest do. My motherboard has 6 holes for standoffs, but because of my cases smaller holes, i could only fit 4, leaving the top left and top middle untouched. Is this a problem and should i force the standoffs through the too small holes?? Any help would be much appreciated.
