Is it hard? and what platform should be used i was thinking kick but im not sure im just looking for something like twitch but not.

idk why but i have the urge to do many things and i guess content creation i sone of them but for gaming. so do i need a powerful pc to start with a quite backround or can i work with a low end pc with a bunch of fans blowing air and sometimes a noisy backround. i could probrably use some advice or tips becasue i would like to do this for fun if possible and i am a bit confused.
