i7 6 Core Build Help?

Hi, so I am in the process of building my first pc. The original idea was for a 2000 dollar 4k gaming pc. I eventually thought that I would want more and be able to do anything I want. So I am now looking at a 3500 gaming/everything pc. Before I make any purchases I want to make sure that the pc components will work and will be a good fit. So I decided on 6 core intel (core i7 3930k Sandy bridge e 6 core 3.2 ghz), for gpu I'm thinking dual gtx 760. For memory 32gb of corsair vengeance pro series. The motherboard is Asus p9x79 intel la 2011 x79. Case is going to be phantoms ethoo pro series. Ssd is going to be samsung 840 Evo 500gb. Hard drive is going to be wd red 4tb for later raid with more wd red 4tbs. Cup cooler is gonna be corsair hydro series h105 extreme. For monitor I would like to get the samsung ud590 series 28" 4k monitor. And a logitech g19s keyboard. I want to try and save some money. Thinking of dropping the g19s and going down to a 250gb ssd and that's all I can think of. I would like to save some money and also know if that setup is good. And what fans I should get as I have not added any fans. Any help would be greatly appreciated. Thank you.
