Opinions before I start buying parts

I'm planning on splurging and putting together a $3k gaming rig for myself. The lovely people of r/buildapcforme were kind enough to put together a part list for me. I checked out the pieces and it looks good as far as I can tell, but better safe than sorry. I'd love to hear some feedback or ideas!
