Perfect Cooling for My Rig

Good day to all.

I would like to hear some advice if the Cooler Master V6 GT CPU Cooler is perfect for my ASRock Z77 Extreme 6. I am worried about the tendency that the cooler may not fit in the motherboard due to its heatsink, I am also doubting of the possibility of sacrificing one slot for my RAM modules. I really hate that.

Thanks.
