You said earlier about the NZXT S340 overheating? I own one and never had this issue however i don't SLI. My only issue is the back panel is a pain in the A** to get off.  

No none at all, my only other issues where the terrible zip ties that came with the case not that it is a issue, I have heard that the cable management straps can be a little flimsy but i never had any issues.  

Seems like two good choices. 7700K and [1070] get my vote. I'd also recommend a 1440 ultrawide if you're able to afford it.

Exactly. PCIE SSDs are much faster than their SATA counterparts. I'd recommend getting the PCIe SSD for boot drive and a large SATA SSD for bulk storage and other programs, if you can afford it, otherwise go for a HDD.
 
I'd also recommend some sort of a redundant setup for your drives, such as RAID1, so you'd be protected against data loss in case of a hardware failure

Honestly you don't need a redundant drive or a RAID setup. I would buy a PCIe SSD for your boot drive, and get a 500gb or so SATA SSD for games.
 
If you still have extra money afterwards, buy a 1-4tb mechanical HDD for mass media storage. Or you can invest extra cash into a 1-2TB external hard drive where you can keep backups of your computer. (this also acts as a redundant safety feature) Just keep in mind to do backups fairly often. (Once or twice a month is fine) @Max_Tech

Oh right yeah that PSU is 80+ gold and I already have a thermal paste 
 
Oh I have had experience with EVGA PSU my last PC EVGA PSU exploded and killed my 960 so yeah I'll stick with corsair
