This rig is used entirely for gaming. I decided to build it around the time the Z170 came out, as an upgrade from my older Sandy Bridge system. Overall, I'm happy with the build, but I plan on swapping the liquid cooler out with a Hyper 212 EVO. It just isn't giving me the cooling I expect. A friend who runs a similar build averages about 10-20 degrees cooler CPU temps while playing the same games. Additionally, I'm not sure I would choose the Gigabyte motherboard again. I'm essentially unable to do any overclocking with the included software without my system becoming unstable. I'm not sure if that's partially due to the inferior cooling provided by my water cooler or the motherboard. Some of the sensors on it throw completely incorrect readings (my PCH shows negative temperatures in HWiNFO64) and memory compatibility seems to be laughable. I tried to upgrade the memory to Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-3000 and the computer just wouldn't boot, even with default settings in the BIOS. It's really disappointing, considering my previous experiences with Gigabyte being pleasant. I recall additionally having some issues getting the M.2 drive to function as the boot drive, but got it to work in the end.
Other than those minor issues, I'm pleased with the build. Some would argue that 27" is too big for 1080p, but that's mostly preferential.
EDIT (3/22/2016): Swapped out the previous AIO water cooler (CM Seidon 120V) with a Hyper 212 EVO, and the CPU is already running noticeably cooler. Where I would previously hit 80+ while playing games, watching Twitch streams and chatting in TS or Discord, it now stays below 65, and the thermal paste hasn't even fully set yet. I'm not sure what the issue was with the CM Seidon, but it simply wasn't working the way it should have been. I will add new pictures of the interior, as well as the actual desktop area with monitors and such when I have a chance.
