Here is what I ended up going with:

• Case: FLOW 6.1 GPU Mining Rig $224.95
• Mobo/RAM/CPU/Boot Drive: GPUShack MOBO/CPU/RAM/Boot Drive $239 - $5 coupon (SAVEDFORUMS)
• GPU: ASUS STRIX Radeon Rx 480 8GB OC x2 479.98
• PSU: EVGA 80+ GOLD 1300W $227.34

Total: $1166.27

I went with ASUS GPU because they have a 1330MHz clock and $30.00 mail in rebate. Sadly I could only purchase 2 at a time.
