Office laptop and League of Legends?

I'm looking for a cheap laptop that I want to use mainly for office work and YouTube videos.

And you should be able to play League of Legends on him from time to time.

Which budget?

Are used devices ok or does it have to be new?

League of Legends runs on a 100 euro laptop (2012 hardware), so I ask.

It is just important to me that it runs relatively quickly (of course it doesn't have to be a high-end device) and that it is quiet.

Budget doesn't matter at first, the cheaper the better.

And can also be a used one. So from the last 2-3 years. But new would be nicer
