That build is much better than the one you posted above, you will notice the difference. It still has flaws though, try this.

I swapped the NEX for a CX PSU by Corsair. I realize I'm going to get called out for choosing an 'unreliable' power supply, PCPartPicker says you will be putting out 467 watts maximum. the CX won't give you any troubles at that wattage and it has a much better trac-record than the NEX. I also replaced the Barracuda with a WD Blue because WD makes higher quality drives imo.
