This is my third ITX build since I gave up trying to transport full-size cases from country to country. My previous build used the Sugo SG06 and an i5 2500k. I was never able to get the cooling under control enough to allow me to overclock it, though.
This time I knew I was going to be using a liquid cooler. I spent hours studying coolers, and decided to go with the Corsair. So far, it has worked flawless.
I went with the ASRock board, having had good experiences with them before. Although, if I were to do it over again, I'd go with Asus' board, as the ASRock board doesn't have an M.2 connector.
I have only modestly overclocked it. I will look to push it more in the future. Likewise, I haven't made any attempt to overclock the video card. The EVGA card seemed to be the only 1070 card that would fit into the case at this time. It fit without any modification, though, I believe I did have to pop off the front and slide it through the opening. If I had been a bit more patient, I would have gone with the 1060, as it fit my intended budget a little better.
Overall, I have been very happy with this build. It's nice not to have to worry about my temps anymore. Although, maybe I just traded worries, as it's possible the cooler starts leaking some day.
