Feedback on new build(so far)

[SquidgyWidget]

I'm looking doing my first-ever build for a medium-level gaming computer with a budget of max $1200. I'm also building with the intent to leave some room to grow in the future. TBH I'm a bit whelmed looking at all these parts. I'm looking for feedback to see if I'm on the right track and if the parts would work together.
