Need some help with transferring to a smaller case.

What I have so far:
https://pcpartpicker.com/list/wPzp3R

The parts I already own are the CPU, GPU, RAM, and SSD.

I am leaning towards this case, but I am also completely fine with a different one as long as it's a similar size or smaller, and white.

I need fan and CPU cooler recommendations, ideally from a matching set (visually), as well as some short braided cables to replace any included ones.

I know this is a lot, so thank you for your suggestions! Please let me know if you need any additional information.

(No specific budget, but keep it in-line with the rest of the build, please. If I need a number, say 500-1000 USD more. 1440p res)
