This machine is mainly for photo/video editing and part time gaming. I really liked the way it turned out and I was pretty lucky on the overclock with both CPU and GPU. I would highly recommend all the parts on this list as they all worked flawlessly together and hold up under a pretty good load.
I was especially impressed by the ASRock motherboard with X99 being such a new platform. The BIOS, UEFI and included software all worked great. I didn't try to overclock the memory other than to use the XMP profile (2666) that G.Skill included so not sure what room is left there.
Intel seems to have a real winner with the 5820k as I have seen it as low as $299 during Black Friday. With 6 cores and great OC abilities I can't complain too much.
I tested the living fire out of this machine with OCCT, Intel Extreme OC, Realbench, AIDA 64, Heaven 4, etc. It handles everything I throw at it with ease.
The H440 case is really amazing to handle the Corsair H105 with push/pull config and still have room for everything else. Cable management is about the only challenge to me with the back side of the case being so shallow. However, with a little effort and some good tie wraps all was well.
The MSI video card is a beast given the price. To be able to overclock to GPU 1.5GHz and Memory 8GHz is flat amazing at these temps. It is nearly silent and even when pushed under the heaviest load it makes only a little noise in this case.
Samsung's 850 pro SSD is pretty awesome itself, but the XP941 at over 1000 GB/s is downright ridiculous especially given the incredibly small form factor.
The G.Skill ram worked flawlessly, but it sure hurts paying this price for DDR4.
As for Windows, I can stomach it long enough to do what I have to do, but it sure isn't my favorite OS. I apologize ahead of time for anyone that might be offended by my comment. I work with Windows, OS X and Linux every day and Windows is definitely at the bottom for me.
I am an amateur photographer so I hope my photos turned out decent.
