CPU: The Intel Core i-7 was an easy choice - achieved a 4.5 GHz overclock with minimal effort. Idle temps are fairly low, sitting at 25 degrees and load temps hovering around 65 to 75 degrees. This is with my fans tuned down to 20% speed. I was able to obtain 19 degrees idle and 58 degrees at load with the fans at max speed.
Cooler: Originally I went with the Corsair H80i AIO, however after a few days of testing, I switched to an the EVGA ACX cooler instead. Ultimately I was able to achieve lower CPU and GPU temps by switching to an air cooler.
Motherboard: I was going for an EVGA - themed build here, so the Z170 Stinger was an obvious choice. I had used the Z87 Stinger in the past and was pretty happy with it. Unfortunately EVGA (for reasons unknown to me) removed the Bluetooth and the WiFi from this model, which really was it's predecessors main selling point. That being said, the Z170 Stinger has been outstanding overall.
Memory: Pretty standard kit of Kingston 16GB RAM, 2133 MHz speed, no overclock.
Storage: 250GB 850 EVO SSD for primary applications and OS and a 2TB WB Black for bulk storage. I have the available space in my case to throw in another 2TB Black drive if needed.
GPU: EVGA (again, sticking with the theme) GTX 980ti FTW. I initially purchased an open box variant of this card. Unfortunately it was running very hot and incredibly too loud; after troubleshooting with EVGA, they recommended I return it. So I ended up purchasing the same one, at retail. Quite a bit more expensive, but I'm happy to say that the temps are as expected, given the small form factor of my case, it runs fairly quite at load.
Case: I selected the Phantek's Evolv Mini-itx case, because it was pretty much everything I was looking for in a case. Small form factor, yet large enough to accommodate high-end components. Also allowing for decent cable management was a plus.
PSU: 650W Platinum PSU from EVGA (theme >.<). 650 watts was plenty for my single 980ti, with enough headroom for overclocking. Modular cables (non ketchup and mustard) was a big bonus as well.
Monitor: Predator X34. This. The main inspiration for the build. 3440 x 1440 of pure beauty. This monitor is amazing, simply put. The only negative was the price tag. I was fortunate enough though to strike an unbeatable deal (20% off) at a local retailer.
Peripherals: Razer fanboy, so had to represent the green. Wasn't quite worth it to buy the microphone, webcam and Leviathan from Razer though...I have my limits.
Misc: Windows 10 Pro, because you can't beat keys for $18. Decked out in Phantek's 120mm, 140mm and 200mm fans connected to a PWM fan controller. Green LEDs inside and out. Burner for my sons music (car rides are so much fun....) and external HD for...well...externally storing things I guess >.<
But wait...there's more:
I've been very pleased with the performance of the build thus far. The 980ti tears through anything I throw at it and it all looks amazing on the X34. It didn't come easy though, as this was by far my most complicated and troublesome build to date. Although large for an itx case, it was still difficult installing everything. I found myself putting something in, taking it back out to make something else fit (rinse and repeat), again and again.
I'm happy with the way it turned out though, in it's current state, it fully meets my expectations. I'll be set for a good amount of time...I think ;)
