Absolute beginner here. Need some general advice.

So my 2019 Laptop is showing clear signs of age. I want to go back to a desktop PC and am trying to decide if its worth building one myself. I am somewhat tech literate, but have zero hands on experince with electronics. How much research and work am I looking at and how much money can I save if I am going DIY? I know this is very vague. I'm just beginning to look into it. Ballpark estimates are totally fine.

I need the PC for some basic image and video editing and if it runs games with a medium settings framerate that would be nice too. I don't need state of the art. A decent midrange workhorse is what I am looking for.

Any basic advice would be welcome. Thanks.
