(The components you have i marked as purchased.)
Few words.
Changed CPU cooler to the same one as used in my Skylake build. Arctic Freezer i32 is 150mm tall and it doesn't have any RAM clearance issues.
Also, Arctic Freezer i32 uses fluid dynamic bearing fan that is far better than the sleeve bearing fan used in Hyper 212 EVO.
From here you can read why i don't like sleeve bearings and why i prefer fluid dynamic bearings,

With Arctic Freezer i32, you can easily upgrade your CPU cooling from push configuration to push-pull configuration with any 120mm fan. I did so on my Skylake build where i first used 2nd 120mm Arctic F12 PWM fan. At current date, i replaced the Arctic fluid dynamic bearing fans with Corsair ML120 magnetic levitation bearing fans to improve cooling performance and gain some eyecandy.
I also kept the HGST (Hitachi) 3TB HDD for additional storage. If you don't need the extra storage then feel free to remove it. But if you like to have extra storage and that specific model isn't available at your location, pick any other HGST (Hitachi) HDD that is available. HGST (Hitachi) HDDs are the most reliable HDDs there are. Further reading: https://www.backblaze.com/blog/hard-drive-reliability-stats-q1-2016/
Didn't change the case. Case supports CPU coolers up to 170mm and GPU length up to 370mm.

You said that you have some components that may not fit in the Corsair Carbide 400C case, care to tell which components they are?
About PSU, 700W range PSU is far too much for your system. Your GPU is 150W, add the rest of the system at about 200W and in total, you'll get 350W. Even if you OC your CPU/GPU and put another 50W - 100W load on PSU, the total would be 450W. 650W is more than enough for your PC. So, i left the Seasonic PRIME 650 in the build.
Yes, PRIME 650 is about 50 USD more expensive than Corsair RMx series PSUs or EVGA SuperNOVA G2 series PSUs but it's also the best 650W PSU money can buy and you can be sure that you do get every bit of top performance for your money.
Here's proof:

Seasonic SSR-650TD
Verdict
The new Seasonic Titanium platform is awesome! The 650 W Prime model offers amazing performance in all areas and super high efficiency. Hands down this is the best 650 W unit money can buy today and on top of that it is dead silent, even under worst case scenarios.
One more thing about PSUs,
Here's PSU Tier list:
http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
From PSU Tier list, you can see that Corsair CXM series PSU is low quality (Tier four) PSU. Corsair did redesign their CXM series and improved them a little bit. At best, the new CXM series PSU is mediocre quality (Tier three) PSU.
Seasonic PRIME 650 that i suggested is great quality (Tier one) PSU and on top of that, it's the best 650W PSU there is.
Corsair CX750M is semi modular with 80+ Bronze efficiency and 5 years of warranty.
Seasonic PRIME 650 is fully modular with 80+ Titanium efficiency and 10 years of warranty.

Seasonic PRIME 650 specs: https://seasonic.com/product/prime-650-w-titanium/
If the Seasonic PRIME 650 is too expensive for you then for cheaper price in Tier one i suggest: Seasonic Platinum 660 or Seasonic X-650. And in Tier two i suggest: Seasonic G-650 or Seasonic M12II-620 EVO.
Only the Seasonic G-650 is semi-modular, all others are fully modular.
