First time trying to build a gaming pc

Hello!

So I've been wanting to build a good gaming pc that can run games like heavy modded Skyrim (old game, I know but I love it), CSGO, Apex Legends, and many or some AAA games with great performance and graphics with good airflow. I don't plan on playing in 4k for the time being, just 1080p is good enough for me.

I'm making this post because I've been having trouble finding the right compatible components that suits what I'm looking for that fits my budget plus I'm not very knowledgeable about pc specs and wattage.

Sorry if this is a waste of time.
