Suggest a good PC for screen record for yt

I want to start a channel on SEO hopefully, but I need to buy an affordable PC to run the screen recording software.
The soft needs to have features of screen record and recording yourself in small scale in the corner.
OBS has it, any other options?

What should I look in PC for software to run smoothly and with good output ? Video Card ? Core? Or RAM ? TX

Minimum Core i5, 16GB Ram, 8gb graphics Card device you can use, For recording obs is best.
