So I'm in the process of switching out cases and I went with corsairs obsidian series, as I go to install my mobo, I'm putting I'm the stand offs but then at the top I notice 2 dome like things on the interior. They have holes to where I could put a stand off in but when I do this and lay the mobo on it it sits at an angle. So does this mean I done need any stand offs since it will keep the mobo off the back of the case?
