Trying to install Soyo P4s Dragon Ultra m/b in Evercase EC4252 case.(first timer) Case has 9 little mounds/dimples for the mounting screws. If I put Evercase supplied spacers in these screwhole mounds, m/b is too high for backplate. If I attach m/b to mounds directly, height is perfect. But only eight of the 9 screwholes on m/b line up with a "mound". So one mound is in contact with back of m/b. Won't that short it out? What am I supposed to do? Nothing in manuals or mfgr websites. Thanks.
