My second mini-itx build, done for my significant other.
I used the thermaltake core V1 snow edition that I already used for my first mini itx build; I liked the case a lot, it was easy to build in and I think it looks great, so it was an easy choice.
For the motherboard I went with a H270, which does not make that much sense with an unlocked CPU, I know I know. I was looking for something not too expensive endowed with an M.2 SSD slot.
The machine will be used for general office tasks mostly and for that it sure is a complete overkill (as is the 650W PSU)... but you never know right, maybe it will run some games too.
The overall build experience was great and I am very happy with the result, especially bringing down the noise level using some resistance cables on the fans was working out great. Booting this thing up is fun every time thanks to the amazing speeds the M.2 is providing and the HUE+ adds to the fancy rainbow-eyecandy experience.
