Lets get this straight: I KNOW THIS COOLING IS COMPLETE OVERKILL FOR THE PARTS I HAVE. It is used for silence while gaming and editing and also I will be adding to this system. Also look at the temps and remember that I am running the fans at 30%.
Now that that's out of the way, I use this for gaming, editing and a lot of overnight or longer renders. I have been working is some 3D programs for a while and for the classes I'm in they sometimes take 72 hour renders. That is the reasoning behind the 6-cores. Now for the fun part: Explaining my mindset behind all the parts. (Note, a good majority of the parts were recycled from a previous build of mine, check my profile for that)
CPU: I got this because I knew I would be rendering a lot, I also got it 2 years ago at only $450, so don't criticize its age. It is still seriously fast and especially with that overclock (that I can push even further when I am willing to bear a little noise.
Mobo: It looks nice and it is very stable. Also, I got it at a discount, I wish it had some fan cure profile in the BIOS but nope, oh well.
Memory: This stuff is black, cheap, and fast. I tightened the timings and brought it down to 1866 instead of 2133.
Storage: The Kingston is purely a boot drive. The Samsung is for programs and games that I really like to play and for temp files. The 1tb is for my main storage and the 2tb is for footage and exported projects.
GPU: Why else would I get, at the time of purchase it was the fastest GPU on the market and it runs nice and cool. It's also a great overclocker. (Update, I think I should have gotten the r9 295x2. That would definitely be powerful enough for me for years to come without upgrade. Regrets)
Case: This is where things get less certain. I would have rather gone with the 900D. This case advertises that it holds a 480mm Radiator on the bottom. While I was able to squeeze one in there, I had to practically take apart the case to do so, I consider it false advertising. Other than that I consider it a great case for the money.
PSU: Powerful, silent. Seasonic.
I would go into detail about my peripherals but I'm lazy, ask me questions in the comments and I'll be happy to answer.
Here's a list of the watercooling parts I used in this build:
EK-CoolStream RAD XTX (480)(x2) - These things are huge, like, bigger than just the 120x4. They are wider, which caused a fair amount of problems when installing the bottom rad. Either way they are extremely effective, and I like the EK logo. Also they have a relatively low FPI so I can run my fans at 29% in speedfan and still get enough airflow to cool everything.
Bitspower G1/4 Silver Shiny Dual Rotary 90-Degree Compression Fitting-ID 3/8" OD 5/8" - V2(x5)
Bitspower Premium G1/4" Shiny Silver High Flow 3/8" (5/8") Compression Fitting(x5)
Bitspower G1/4 Silver Shiny Dual Rotary 45-Degree Compression Fitting-ID 3/8" OD 5/8"(x2)
EK-Supremacy EVO - Nickel (Original CSQ) Nickel/Plexi
EK-BAY RES D5 Vario (incl. pump) - This pump works fantastically and quietly. It gives me a fairly good flow at it's lowest speed and it has no issues with the pastel coolant that I use.
PrimoFlex Advanced LRT 10ft Tubing - 3/8in. ID X 5/8in. OD - Crystal Clear (can't recommend this actually. It didn't fit in the Bitfenix fittings, the OD was too large. I ended up buying some XSPC UV tubing, and yes, I will be adding some uv lighting. )
Overall, watercooling was a fun experience and now I do everything in near-silence. My old PC was extremely loud and obnoxious, I can't say the same about this.
