More motherboard mounting holes than motherboard standoffs

[RMinor]

Hi, I am installing a GIGABYTE GA-Z77MX-D3H micro ATX motherboard into a Fractal Define R4 mid tower case. On the motherboard there are 7 holes to screw the motherboard into the standoffs, but these only line up with 6 places on the case where I can append the standoffs.

I've heard the standoffs supply ground to the motherboard (though I would guess ground would come from the power supply too). Am I risking anything by having only 6 of the 7 spots grounded to the standoffs? Will part of the motherboard remain precariously ungrounded?

This is my first build. It seems I got a case too big for my needs, but other than this problem everything else looks good. I haven't booted it up yet because I'm nervous about messing up the motherboard or something. Any help would be greatly appreciated. Thanks!

No to both. You'll have no problems.

Thank you!

I have plenty of standoffs, the problem just comes from the case not having a hole in the right place where one of the standoffs should screw in. The motherboard still seems very secure with just the six standoffs though (I'm using the stock cpu fan and no graphics card, so there isn't a whole lot of weight) so I think it should be okay.

I think the problem may be because I have a micro ATX motherboard paired with a mid tower case. Though the case did say it was compatible with micro ATX, mini ATX and ATX. Who knows.

Thanks!
