Gaming PC for 350 euro from used parts?

Can you put together a pc for me for 350-400 euro? Would buy the parts used too.
The pc should:

-Fortnite run at 90-100fps

-GTA V at 60-70fps

-Minecraft at 100 fps

Minecraft at 300 fps is unrealistic for the budget. For 500.- I built this pc:

-Ryzen 5 2600x

-GTX 1650 great

-16 GB DDR4 Gskill Aegis

-Aorus B450 Elite RGB

-500w power supply

used that could reach 400-300 euro. Maybe you can find all of this as a bargain.

Why do you need 400 fps in Minecraft?

Do you even have a 144hz monitor?

Yes I have.
