I have the Fractal North with the mesh side panel, fell in love with it when I saw it. It really is up to you to decide.
Heres a potential build for you, if you wanted to push for closer to 1700, you could swap in an RTX 4070 instead. Others here may have ideas here as well, I havent been following parts as closely as some do, but this has good quality components and would do well. You may need to pick up a case fan or two extra, Arctic F series are good and cheap. As for RGB I dont really know as its not my thing, but most major brands are probably OK.

The case really is a matter of personal taste when we are talking about Fractals range, just read some reviews look at pics and choose. Nothing to stop you changing it later on if something new interests you.
