Great build but a few things:
1. If you aren't planning on overclocking there is no reason to get a K processor. K processors have their multipliers unlocked, which means they are designed to be overclocked. For simplicity's sake, K skus are the only overclockable intel processors (you can overclock non K processors but its more difficult). I would save some money, 120 bucks to be exact, and just get an i5-6500. It's a great processor and will do everything you need it to do.
2. The motherboard is great but its overkill. You could save quite a bit of money if you buy a cheaper one and then get an external wifi stick. If that's a deal breaker than the motherboard is fine.
3. That power supply is also overkill. It's more wattage than you'll ever need with this system and is even too much if you decided to add another graphics card.

How about this? Or the 650w version for 100 even. They're 80 plus gold, they're fully modular, and they'll be more power efficient because your system load will fall into a higher percent load of the psu, which is more efficient. Put another way, if your system draws 350-450w at max load (which is what I would expect) your PSU will be at about 70 percent load with the 650w vs under 50 percent with the one you chose. The 650 or 750w PSU still give you room to upgrade as well.
4. Why Windows 10 pro? Home is cheaper and will have all the features you need. Pro just adds deeper encryption, virtualization tech, and domain tech (for networks and things across multiple computers).
5. Is there a particular reason you want that monitor? You could go 1440p or even 4K for less.
Just some final thoughts. I understand your desire for dependability, but I almost always recommend overclocking. My desktop has an i7-920 which is an 8 year old chip. I've had it heavily overclocked since day one and I think that speaks volumes about the effect of overclocking on dependability or lack thereof. I'm a gamer, and OC'ing allows me to squeeze more use of out my hardware before I need to upgrade. In addition, it just makes the computer faster in day to day use. You could also hold off on OC'ing until later down the road, when performance starts to lag.
