Which PC / laptop should I buy?

I currently have the problem that I can no longer get there with my Lenovo T440 with the i5-4300 and the integrated Intel hd graphics and now I need a new pc. However, I only have around 300-400 euro if the old one would be sold and at the moment I don't know whether I should buy a standpc or a laptop given the price. Minecraft and Fortnite should run smoothly and not (Minecraft) jerk or (Fortnite) be unplayable. I currently have 8GB RAM installed. Could someone suggest me something good?

There's nothing
