Budget CAD design workstation build

Hello, I'm trying to build a CAD workstation for myself, I need it to be able to handle Inventor and Autocad maybe some basic gaming. I don't need it to be fancy since I use my laptop for most of my other work. I also would like to make it relatively small and good looking. Pereferrably under 1k.
From what I know, since CAD is mostly a single thread task, Having a faster CPU might be better so I'm looking at overclocking as an option.
Here is what I got so far,

I really loved this case and would prefer to use it in the build so thats probably the only place I cant cut costs, I aslo happen to have 10-12 HHDs that I can use so I don't need to buy any.

Appreciate any help!
