7 x XFX RX480 8GB - MSI Z170A GAMING M7

Hi,

I'm planning to build my first mining rig using following parts:

CPU: Intel Celeron G1840
M/B: MSI Z170A GAMING M7
RAM: Corsair Value Select DDR3 - 4 GB
SSD: Intel 540S 180GB
GPU: 7 x XFX Radeon RX 480 GTR Black Edition 8GB
PSU: EVGA SuperNOVA 1600 P2 power supply - 1600 Watt

Case: Rosewill RSV-L4500 (will custom mod it)
PCI-X reiser: 7 x USB powered via 6-pin (not SATA)

I was originally thinking about Asrock BTC motherboard and 6 XFX cards but I might as well pack maximum I can in a 4U chassis Also PSU might be a bit overkill but I want to avoid running two smaller PSUs.

It will be hosted in a proper datacentre with very good cooling (cooling alleys etc)

Any recommendations / suggestions?

Thanks
