£1k Gaming PC Build For My Nephew

[Hobbsie]

Hi All,
My sister is looking to buy my nephew his first gaming rig and has come to me dabble but not great at specs of components etc.
So he is now 14 and is starting to get into all types of games (not just fortnite as they all seem to be in these days)

Budget is £1k and he has nothing so needs it all OS, monitor, Keyboard, Mouse.
Also need to be useful for school work as well.

Hope this is enough info for some help with this please?

Thanks in advance

Thank you @lee32uk and @Quartz appreciate it.

I believe he has headphones i am told the ones he uses at the mo for his xbox will work with a pc, he shares his room with his brother as well so headphones may be a great option at times.

Thanks Again.
