New computer - Suggestions / Doubt

[[TC-R] Renegade]

Stock coolers are fine, although they're very loud at times. I'd recommend a Noctua NH-U12S if you want an air cooler and something like a Cooler Master RL-S12V-24PK-R2 if you want a closed loop liquid cooler. The Noctua air cooler will be quieter but the Cooler Master liquid one will be cooler by a few degrees.

As for myself, I have a Corsair H80i and two Noctua NF-F12PWM fans sandwiching the radiator. My PC now virtually silent with my FX-8350 overclocked to 4.5GHz, I can't hear my PC and it never goes above 55°C (under 100% load for about 25 minutes). I'd say get what I have but you can get almost the same for a lot less money. I bought mine about a year ago.

As for storage, I would go with something like a Samsung 850Pro SSD for your OS and a few games (256gb), Kingston SSDNow's are decent don't get me wrong, go with what you prefer, the 850 pro's are a bit more expensive, but have better read and write speeds by about 100MB/s

Processor and ram looks good however, it's up to you if you want to go with something a little newer like a 6700 (non k if you don't plan on overclocking), a Z170 motherboard and some DDR4, might make the build a little easier to upgrade in the future if need be, also would make it a little more future-proof. Not sure what effect this would have on the cost though.

As for the PSU, I'd go with something better like an EVGA Supernova 750w G1 or G2, that way you could buy a second graphics card in the future and take advantage of SLi without running your PSU above it's recommended load. Corsair CX750M's are 80+ Bronze. That's not bad, I used to have a CX750M, but I'd go with something more solid (80+ Gold) and fully modular.

Edit: I thought you were going with a CX750M, not a CS750M. I can't read, they're the same apart from the CS is 80+ Gold and the CX is 80+ Bronze, both are semi-modular. You'll be fine with the CS750M like you planned.

GPU looks good, my little brother has a 970 (Gigabyte Windforce) and he has had no problems with it, he also has the same case as you're planning on getting too. Secondary HDD looks alright too. That's my two cents.
