I want to buy a gaming PC I have no idea, can I make suggestions or advise?

The PC should not be too expensive so I pay for the PC myself (I'm still a student)

A price range from 700 to 800 euro is ok

I want to play games like Fortnite, CSGO, Valorant and Gta.

Build it yourself or buy it ready?

If you build it yourself, it will be a little cheaper

I don't know how to assemble a pc

At dubaro there are always 2 youtubers who buy their pc suggestions, there are always new ones.
