Was going to ask why the z170 board and then say the $110 price which is better then most any full size h170 board.
Bild looks pretty good, I have the R4 and love that case.
For gaming the 1050 ti is pretty weak vs the rest of the build. If this is for video editing, phototshop or other purposes and not gamign then the 1050 ti is a good choice to make use of CUDA cores without dumping much more money into it. If thi is is for gaming then I would at least try to step up to a 1060 3GB model.
