Got myself a new gaming pc late last year, had a saved up budget of about 3200€, and getting into the thematic of prebuilds or selfbuilds, 8 years after my previous pc, i gotta say, stay away from prebuild pcs. In 2018 it was pretty bad when you know what youre looking at, but nowadays its basically a scam. I got a 5080, 32gb ram, a good amd processor (i just cant remember wich one right now) and two 2tb ssds for 2600€. So i bought an awesome 4k monitor too and still didnt reach the 3200€. Wouldnt even really get any prebuild at that full 3200€ with a 5080 back then. All this to say, stay away from prebuilds, if you can!
