Need help before making a purchase

So I was thinking about buying a gaming laptop for 1800 euros, but after thinking about it I thought what's the point? Why not just get a built pc? And so now I am looking for 32gb ram build pc's and I need help on getting one that's 2000 or less since I will also need to get a monitor and a keyboard. This would also be my very first time owning and building a pc if I need to build it. I've been a console player all my life so I want to learn as much as I can.
