PROS: Overall this build was pretty good and I'd recommend it if you want to build a moderately priced machine with great performance. Cable management in the Fractal Define R5 was good, but not great and it's something I still have to work on but all of the components worked well together. The H100i GTX was super easy to install for the 2011v3 socket since the mounting plate is pre-installed. You just pop in the standoffs then screw down the pump.
Asus Motherboards are renowned for their quality and this is my first. I now see why a lot of people are willing to may the few extra bucks for Asus. This board is awesome. Built in Power and reset switch, LED code display so you can see where an error is (if one occurs) and plenty of slots. The X99-A has all the bells and whistles of an enthusiast board but for a moderate price tag. Overall very happy with this.
I've always used G-SKill RAM and I've never gotten a bad module, so thumbs up there.
CONS: I'd recommend a different Seasonic PSU. The unit itself works great, but since it's only semi-modular, the 20 pin and 8 pin CPU connectors BARELY reach. The CPU connector in particular can't be run through the back of this case because the cable is so short. Not Seasonic's fault, but be aware.
Currently (as of this writing) the cheapest DDR4 CPU you can buy (at least if you buy from Microcenter -- $299 baby!). Skylake CPU's are more expensive and do not have much a difference in performance. 6 Cores, very easy to overclock with a good motherboard.
Easy assembly, especially on a 2011v3 slot. Great performance.
All the bells and whistles of more expensive board without the price tag. Legendary ASUS build quality.
G-Skill delivers as always. Never had a bad module from them and this model is specifically listed in the Asus x99-A manual as compatible.
850 Pro Performance without the price.
Very impressed with this case. Comes with pretty much anything you might need, ample room for drives and peripherals, solid cable management, good airflow and it's QUIET. I barely even notice my PC is on in a quiet room.
