Case Standoffs Question

[Rhescape]

So today i just got the NZXT S340 Red/Black Case and i have a pretty "stupid" question: the standoffs are preinstalled in the case for a standard ATX motherboard, however, there is one that is just like a nub or sticks out that you can't screw anything into. So here is my question: Do you remove this while installing or is it safe to leave in and just ignore. Basically, can i just ignore it and screw in the Motherboard using the 8 holes around it and will that be safe? Thanks.

You leave that one.It is a positioning nub.
Used to assist in getting the motherboard in exactly the right place to screw the first screw in.
