Need suggestions with this build.

Budget is around 2k euro.
Was picking up parts in dollars, but I'm living in Ukraine, so this prices will just transform in euro, since everything costs 10-15% more here.

Rest of budget is for case and monitor. PSU - 850W, because I'm going to add 2nd 980 with SLI later. Can stretch up to 2200$. Peripheral not needed.

Strongly need suggestions for case, since I'm bad in picking up correct PSU form factor, as well as I don't know the sizes, in case of going in future with 2x SLI gigantic cards - what towers they will actually fit.
Also need some suggestions about noise level in my build, maybe someone was running with similar CPU cooler or 2x 980s.

Any advice or comment will be greatly appreciated.

For starters you don't want to buy sticks of RAM individually. Buy a matched set that way if there's a bad module it will be much easier to determine if one or the other is faulty. If you've got a $2200 budget I would do something like this:

Then with the difference add whatever monitor, keyboard, mouse, and OS you want.

Difference between ASRock x99 and MSI x99?
About RAM - didn't notice there was 2x8 option on PCPartPicker (also question - any difference between 2x8 or 4x4?)
