Researching hardware for my next 5+ GPU mining rig.
Case: aluminium open case (custom made)
Motherboard: still researching but ASRock Z87 Extreme9 looks like it will do the job
http://www.asrock.com/mb/Intel/Z87%20Extreme9ac/GPUs: 5+ Sapphire Toxic Radeon R9 280X (currently my first choice but also researching R9 290 options)
PSUs: 2x 1000W+ Corsair
Core i3 CPU, 4GB RAM, Xubuntu booting from Sandisk Cruzer Fit USB Flash Drive
Any advice will be appreciated!
