The Rigs

MotherBoard: Gigabyte Z87X-OC CPU:Intel G3220 RAM:Kingston HyperX Lovo 8GB HDD: WD 500GB GPU: Sapphire R9 280X (x3) PowerSupply: Corsair AX1200I

MotherBoard: ASRock Z87 Extreme4 CPU:Intel G3220 RAM:Kingston HyperX Lovo 8GB HDD: WD 500GB (Laptop HDD) GPU: Asus R9 280X (x3) PowerSupply: Seasonic 1250W The first setup averages around 715mh/s while the 2nd setup avearages 735mh/s, price difference per graphic card is around $75 to $100. On a personal note i will recommend to take the sapphire, which is more value for money. Please get the crosair AX1200i and no other power supply, corsair has proven it can deliver the voltage. the seasonic i am using has under volted one of the graphic card as it is not able to deliver the voltage when i input the command (--gpu-powertune 20)which i find it surprising (will talk more on the settings of the miner and the different types of miner in the later post). My personal is to get a mother board that has good spacing between PCI-E slots so that the cooling effect will be better. Gigabyte motherboard has good spacing but will be on the pricey side, ASROCK is more value for money. Remember to configure on your bios to manually set the PCI-E slots to Gen 2 for all cards leaving only one card on Gen3, (note do not let it go on default mode, will cause hardware error and system may not be able to startup. (will touch on more on initial Setup of the system) For the Hardisk do get the WD 500gb laptop version easier to manage, there is 2 version of this hdd do then the cheaper ones as it saves cost :). Windows if possible do make a bootable USB thumbdrive as the installation speed will increase significantly like half the time taken for a CD to install windows.
