Need help with first PC

I have recently wanted to upgrade from my acer laptop into a PC but do not know what to get. I have a budget of around $1.5k (it's fine if it's over budget). I plan to mainly play video games, VR games, maybe stream/record, and definitely work with CAM and CAD software's. Preferably a PC that once built, I do not have to think about upgrading for many years. I don't currently own a monitor at the moment, so whatever you feel like is the best. Also the only requests I have are, if possible add a DVD player support and I would really like to have Iron Forge's strawberry milkbox case if possible. Thanks!
