help please, i have my mpower msi (ATX) mobo, and im a bit confused with installing it into my 750d, cause I've found that in 750d there is a middle "stand off" which helps to get mobo in place for a better contact with AIO shield or whatever it is for..the problem is that i have only 8 stand offs(they were pre applied) and this 9th stand off( in the middle for the ATX screw base). Should I install it only on 8 stand offs and ignore this screw which goes through the mobo?
