I'm a casual gamer and an architect but spend a good deal of time photo and 4K video editing. I recently upgraded my old monitor with an LG 32UL950 4k IPS panel. It's only 60Hz but color accuracy is much more important than frame rate for me. I've never used a monitor over 60Hz so I don't miss anything with this selection. The monitor will be shared with my wife's macbook so the Thunderbolt compatibility is a bonus.
This is my first micoATX build and a significant step up from my last build back in 2012 which was a 3930k and an EVGA GTX 680. I settled on the Phanteks Enthoo Evolv TG for looks and because it could hold a 280mm radiator, GPU's over 300mm, plus 4 hard drives. It's a very spacious case but cable management in the back was a challenge with the RGB controllers and extra cables that come with them. If the back panel was fastened with thumb screws instead of magnets, cable management wouldn't be so important. As designed, if the cables aren't super flat, they will keep the back panel from staying shut. That's my biggest complaint with the case.
I delided the 8700k and overclocked to 5.0 GHz. Temps are in the mid 80s while stress testing with Prime95. I'd benefit from push/pull on the radiator but that won't fit in this case unless I removed my 3.5" drives. Alternatively, some better performing fans would help drop a degree of two but I'm choosing form over function with this build. The airflow in this case is a bit lacking overall. I tried removing the top lid during stress testing to see how the case design was restricting airflow and temps dropped about 3 degrees. I saw this reported in some online tests so I knew what I was getting but it's always interesting to test and see it first-hand.
The Kraken X62 blocks one DIMM but luckily I only need two. If I need to expand in the future, I'll rotate the block 90 degrees then turn off the NZXT logo.
