Should I change anything ?

Solution
Your first build is fine. But I agree about not needing the gpu unless you are gaming. And like the others I'm not a fan of the power supply. But I'm not as against using a cheap power supply with a cheaper PC as many people might be. If you skipped the graphics card and went with the above mentioned 2400g I would think a cheaper power supply would be fine (Not preferred, but if you wanted to save the money you could get away with it).

Why they are recommending the 2400g is because it is very decent for multi tasking and it has the best built in graphics of the cpu's. So if you did want to play some games it can handle them at lower settings.
If you're not gaming the GTX1060 is redundant, it's just wasted money, and the PSU could better, although the full SSD storage looks sweet.

There's only 2 things actually worth changing and keeping the same build idea. That psu needs to go. There's ppl in China laughing till they cry at the thought of someone purchasing it. Offset the difference with a Rx580 gpu instead of the gtx1060.

The BT is fine for an office type pc, if using nothing more than integrated graphics. Once you add a decently expensive gpu, that's a whole different beast. Gpus can and do put tremendous stress on a psu with almost instant high/low/high demands, such as going from 150w to 15w to 150w 100x a second or more. The old Corsair CX is a great example. For an office, stock replacement it was great. Cheap, good thermals, reliable. Slap a decent gpu on it and you'd be lucky to get 18months out of it.
