Do 6 rigs. 3 cards per rig.
PSU min.1000w golden/platinum efficiency, could use two 750w powers also but considering you are noob, I wouldn't start with two PSU. Google this.
Undervolt your GPU's. Google this.
Ram 4-8Gb 1333 DDR3 /rig
HDD: NO hdd use litecoinBAMT and usb-stick. Google this
Remember to use only two rigs behind one fuse. So you need at least 3 individual supply-lines from your fusebox to your rigs.
See that there is no other load behind those fuses.
You will need allso risers for your GPUs and a case of some sort. Google this
Thanks for everything. Also, i plan to use this:

Will that be cool?
in my opininon you shant give bad advice. You can have 8 gpus if you manage to find big bang marshal motherboard. You can do even more if you have pci-e splitters.
