Hi there. I'm trying my first build and I've run into an issue. My Corsair 300R case looks a little different than the photos on Amazon and the Corsair site. Their photos show little stamped raised areas instead of standoffs for the motherboard screws. The case I received from Amazon does have standoffs instead of the raised bumps. It also has a post near the center of where the motherboard should sit. This post is taller than the standoffs. I don't seem to see a hole where this post could go through the motherboard? I'm using an ASRock Z97 Extreme3 motherboard. It looks like that post can be unscrewed and there is an extra standoff included. Should I just remove the post? Do I need to replace it with the standoff to support the center of the board? Thanks for the help!
