1. you don't need a K series CPU sku for gaming it's completely unnessesary unless you plan to content create or whatever. Most games don't need all that CPU power.
2. be warry of tall CPU coolers, they can often block your DM slots and thus you can't install your RAM. Probably smart to go with LPX Ram OR go with a small factor cooler, Nocturna makes good ones.
3. I'd say a safe bet PSU for a good upgrade path is 750W. Good for now, but you'll want a full modular 750W pSU when it comes time to upgrade your card.
4. Get a bigger capacity SSD.
5. if you are willing to sell out that much for a KB get a better kb qaulity. but thats personal preference so you dont have to listen to that.
6. Keep in mind what resolution monitor/ display you're intending to play on. Granted I truely believe D2 is going to be optimized well as shit you'll want to keep that in mind. if you're shooting for 1080p at 60fps barring there arent a lot of things you'll have to render you shoul dbe ok, at high/ possibly ultra settings. Destiny's particle physics are going to be fucking Gorgeous on pc, but insane as they always are.
7. That's a decent case, i did a buid with that exact model for my father in law christmas last year, but cable management in it is absolute trash. Check out the Corsair Air series. I always love dual chamber.
8. pro tip I personally use. I put all my executables and programs on my SSD and install all of my games on an HDD. 2-3TB is a good capacity.
As a planning phase this is pretty damn good.
