Reddit mentions of RaceFace 104mm Single Chain Ring, Black, 34T 9/10/11 Speed

I mean the real ones are like $13 dollars more, don't buy unnecessary food/coffee/drink/whatever for a week and you've recuperated the cost of wondering. https://amzn.com/B00D3FG6ZW

I scored this Rockhopper for $50! Now I’m looking to modernize pretty much the whole thing. Please critique my build list below. Would you get anything different, or better, or maybe anything else that would be better value? Did I miss anything? Do you think all of this will work together? It will be my adventure bike for bike packing, gravel, off road touring.
