This is what I would recommend. The MSI SLI Plus is a pretty decent motherboard with good features and the 5820k is the least expensive X99 CPU you can get, though still a very good one especially at only ~$30 more than the 4790k. I went with an 850 evo for your boot drive and a 1tb WD Blue drive for mass storage. I chose 4x4 memory for quad channel and though 8gb is enough for games, I went with 16gb just to be safe and also in case you ever want to go into more intensive things. The case I chose is the enthoo pro, great full tower case at a very competitive price and building in this will be easy. For the power supply I went with my personal favorite, the EVGA G2 850W, excellent quality at again a competitive price.
