Antec vs Corsair Case, Deepcool vs Corsair Cooler

I wouldn't get either components. Mind sharing where you're located, how much you have allocated for your build and where you'd like to purchase them from(preferred site)? I think we could source parts using PCPartPicker with much effect.

You forgot to include the ram, SSD/mechanical drive and PSU to your parts. Also, you could go for an matx build if you're only looking at one GPU(and no multi GPU later down the road).
 


Well, which micro-ATX. My options are limited because I am in India and imported stuff I can't afford. here are my options:

Location: Hyderabad, INDIA
Preferred Website: https://www.amazon.in/
Overclocking: No OC-ing. No games
Work: Programming, Data Science/ML, Jupyter Lab, 1080p/Bluray/HD movies, watching live 1080p streaming on YouTube

I put my list at PCPartPicker like you advised
 


PCPartPicker advice was good. Thanks
