Sim gaming PC for 2000 euro?

Evening together,

the question is addressed to the simulation racing community. I would like to switch from the game console / PS4 to a gaming computer in relation to simulation racing. I currently lack the basic knowledge of which components could be used, so I would rather rely on a ready computer, I was thinking of a Mini-ITX PC. My budget for this is 2000 euro, maybe someone can recommend me something good here?!
