Advice on new PC build designed for 4K gaming / VR

Hello all, looking to embark on my second ever PC build. First went really well for the last 5 years, but I'm pretty sure I'll be getting into VR (leaning towards HTC Vive). I could probably just upgrade some components, but I'm the type who would rather just start from scratch. Using the outline from the sticky, here is some initial information:

Approximate Purchase Date: within the next couple weeks

Budget Range: ~$3,500 - $4,000 (including monitor)

System Usage from Most to Least Important: Primarily gaming, and I'm thinking VR will become a significant portion of that.

Are you buying a monitor: Yes

Do you need to buy OS: Yes

Preferred Website(s) for Parts: Newegg.com (really wish I had a Frys close)

Location: City, State/Region, Country - Eastern North Carolina, USA

Parts Preferences: Prefer Intel CPU and NVidia GPU. Pretty open beyond that.

Overclocking: Maybe

SLI or Crossfire: Maybe - looking at SLI but would like opinions on its worthiness

Additional Comments: Primary goal is a killer gaming/VR machine from a functional standpoint, but I'm not averse to spending a little extra cash to have it look cool.

Here's what I've been looking at so far, but really not locked into anything yet at this point:

CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819117403 ] Intel Core i7-5930K Haswell-E 6-Core 3.5 GHz LGA 2011-v3 140W BX80648I75930K Desktop Processor [/url]

Cooling: Could use some help here. I've been looking at a CLC system, but I'd probably rather lean towards solid air cooling to keep things simple. Never used any type of liquid cooling before and I'd prefer to avoid it. I don't plan to do any extreme overclocking anyway.

PSU: Another place I could use some help. Just want something rock solid without unnecessary overkill.

Case: I could use some advice. I've looked at these:

Monitor: Again, I really could use some advice here as I am pretty unfamiliar with display technology.

I think that's about it. I really appreciate any help y'all can give! One thing I really want to avoid is spending the time gathering components only to find they aren't compatible, don't complement features of each other, or physically don't fit. Thanks so much!
