Need help w/ ASRock FM2A85X Extreme 6

[ManicWZRD]

I just got the ASRock FM2A85X Extreme6 motherboard and it appears that the motherboard has 10 grounding points but my case only has the usual nine, do I need to connect all 10 or can I get away with only connecting 9? Or do I need another standoff?

I never use the 10th one back close to the I/O ports and slightly below them. The normal 9 are in line at both ends of the board and the middle row is closer to the bottom of the mobo. That tenth screw hole between the midddle and lower row is the one I never use.
