Build Advice: 4k gaming in the living room (Cooltek W2 case)

Thanks for the comments.

I have changed the cooler as you suggest, thanks for the tip.

I appreciate 16gb of ram is not really necessary for today's games but thought that it might be helpful if I want to have things running in the background or if tomorrow's games start to use more ram (2x4gb version of the same sticks are USD95 cheaper, I don't mind this against the overall budget if it might be handy from time to time and I am an absolute sucker for the more is better argument on RAM size for some reason). I would also be very interested to hear your opinion of the particular choice of ram. I am not really sure what the best clock speed / latency combination would be but I have read 1866 is the sweet spot. If I saved the USD95 on shifting to 8gb is there a better set to get, preferably without a heatsink as you suggest.

On the SSD, I wanted something reliable from a quality manufacturer. The cheapest 256Mb SSD on the Tsukumo site is the Adata ASP600S3-256GM-C-R2 which comes out USD 94 cheaper, I don't know much about Adata but some reviews seem to suggest they are solid although Samaundg has a very good reputation. I don't want to ruin the build by skimping on one part. I have scaled back to a Samsung 850 EVO (USD 43 saving), the 840 EVO is not in stock at this size.

The mobo was my big extravagance, I know I will not really work it hard enough to justify getting a high-end board. The cheapest Z97 with SLI support I found from Tsukumo was the Gigabyte GA-Z97X-SLI (USD 90 saving) which seems solid enough. My reasoning was that as I am not an experienced overclocker but want to experiment with it, I could use all the help I could get in terms of rugged components and additional features/software so might as well spend the extra money. I also, perhaps mistakenly thought that this board would be a little more future proof.

On the ram fitting I assume you have experience with a Noctua NH-D14. Is there much clearance? Hopefully I can get a better ram choice with no heatsink and this will not be an issue. The choice of no heatsink memory @ 1866Mhz seems relatively small I found Corsair Vengeance (http://shop.tsukumo.co.jp/goods/0843591039208/201010014000000) 16GB(8GB×2)、CL=10-11-10-30、DDR3-1866MHz The vengeance pro (as selected above) has CL=9-10-9-27 does this have much impact?

I will be maxing out on case fans but want to see how good the stock fans are on this case, the reviews suggest they are pretty good. I also thought this was a good reason to spend more on the mother board as it would give better control over multiple case fans, is this right?

Looking forward to any additional help you can give me, or any comments from other users.

Thanks for the help. I have updated the list, looks much better value now:

You have saved me a nice chunk of money which is much appreciated, but to spin it round, if you were to spend the, say USD200, you just saved on making something better what would you spend it on?

Is X99 a complete waste of money or might it be handy for future proofing? Are there any benefits in performance or features now?
What are you views on a closed loop cpu cooler instead (will be quite a cramped case and I want it to stay quiet so might need all the cooling help I can get).
