Computer for watching videos and surfing the web at minimum cost

[MoistPotato]

My dad keep insisting me to build him a computer, but I only know to build since I just upgraded mine. The thing is that i don't know the best parts to get for just surfing the web and watching videos. I need the lowest cost, but good fast for surfing the web and watching videos

You don't need much. Insist it on the Processor, focus more in it to avoid lag.

get a chromebook for him if he doesn't need to run local programs.
