New to Mining

I have been reading up yesterday and pulled the trigger on a mining rig. I initially was going to go for 6 x rx480 GPU's but decided on getting 4 then ordering another 2 once it is up and running.

I have ordered the following

• 1000W Corsair HX1000i High Performance 80+ Platinum Digital Power Supply
  
• 120GB SanDisk Z410, 2.5" SSD, SATA III - 6Gb/s, SLC/TLC, Read 540MB/s, Write 405MB/s, 35k/55k IOPS
  
• ASRock Z97 EXTREME4 Intel Z97, S1150, DDR3, PCIe 3.0 (x16), Quad SLi / 3 Way CrossFireX, D-Sub, DP, DVI-D, HDMI, ATX
  
• Intel Celeron G1850, S 1150, Haswell Refresh, Dual Core, 2.9GHz, 5 GT/s DMI, 29x Ratio, 54W, CPU, Retail
  
• 16GB (2x8GB) Corsair DDR3 Vengeance Pro Series Red, PC3-14900 (1866), Non-ECC Unbuffered, CAS 9-10-9-27, XMP, 1.5V
  

I have also ordered some USB risers for the cards as i intend to mount them on an open frame made from wood.

The next step is to get the software side of things sorted, i will be using linux.

Does anyone know what is the best pool to start with?

Thanks
