Hi, so I'm currentlding a PC right now and I'm kind of confused. It's my first time building a PC but the case I think doesn't have the traditional standoffs where you actually place them. I got two of the traditional standoffs but where I could place them on the case doesn't have hole on the mobo. And the holes where I should put the standoffs are raised so I'm guessing I don't need to put any standoffs? And just put screws on the holes? I'm using a MSI G43 z77 ATX mobo
