Wow guys, this is a really noob question but...do I need to use washers when installing my mobo? I ask because most guides online don't use them, on my first build I used them..

If I do need to use them the arrangement is as so:

standoff>washer>mobo>washer>screw into standoff

So basically one washer ontop of standoff, mobo sits on standoff + washer and screw with washer below head goes into mobo + standoff. Right?
