First time build multi purpose pc

Ok, I posted a couple days ago and I have done a little more planning on my first pc. First off plan on using this pc for light gaming, I prefer frames over resolution, and will be using a 1080 monitor to start off with an upgrade in the near future, I will also be using this pc for editing 1080 video and rendering 30+ minute videos, and lastly I like to fiddle with some heavy 3d modeling and game design aspects. My current pc struggles to hold up to this task even at the most basic levels with an i5 and 6gigs of ram (several year old laptop). I would like to use 32 gigs of ram just for this use and for future proofing. I must have (non negotiable) 5 usb, 3 of which must be 3.0. I dont know if this will get me there but thats why im here. I plan on trying some light over clocking on the cpu just to learn how to do it. Also noise is not a concern as i game with headphones at all times and listen to music when doing other work on my computer. I'M making the move from console to pc gaming with this rig and am pretty excited to get going with it... that said here is my initial idea with my 1500 dollar budget

If I overlooked some things try to go easy on me as this is my grand entrance to the custom pc scene. ANY recommendations or tips are much appreciated. Also I still need a mouse and keyboard, open on mice but I want a very precise mechanical keyboard with heavy keystroke... also are sound cards still a thing or do we not worry about that anymore (I know I'm a noob) but when I was djing we always had multiple sound card setups in our computers.
