Ryzen is definitely fine. AMD is currently the way to go for budget mid range builds. I just made this quick as for reference. Cases and psu's you can usually find deals on like the examples here. 2200g is a fine entry lvl cpu. If you can squeeze the extra 60$ the ryzen 2600 would be nice to have. The rx570 gpu is also fine and about 50$ less if you wanted to cut costs.
