I have an enlight 7237 case. I have 2 types of connectors for connecting the MB to the case. One is kind of a square metal bracket that clamps in to the bottom of the case and has a hole in the top for a screw. The other type is a metal standoff screw with a hole for another screw on the top. Do I need to use both of these types of connectors to connect my MB? Is it fine for them to touch the bottom of the MB as long as it is only around the holes on the MB? Can anyone else with this case help me out?
