Mobo: MSI Z87 G45
Processor: i7 4700K
Ram: 8GB-16GB (You can do whatever you want)
Case: I like the NZXT Phantom 410 or 001 (your choice of cases, use mid to large ATX cases)
Hard Drives:
SSD: use the Samsung EVO 120 GB for your OS and some select programs
HDD: use 1-3 terabytes because it is cheap
CPU Cooler: Use a corsair H50, they are AWESOME!
Power supply: Use around 700 watts, for future upgrades
GPU: MSI Twin Frozr 750 or 760
USE SSD FOR OS! IT WILL GO VERY FAST!
Good luck!
