sooo im switching from a 144hz xbox series s set up to a full on pc. my budget isn't very tight, it's 7000 usd (I can get more if I sell my xbox and monitor, but I wanna keep them. also I'll be using the 144hz aoc monitor along with a 240hz one in a dual monitor set up.) I just need help with everything. I don't know which case to get, which monitor to get, which gpu to get. I only have a keyboard and a mouse ready, lol. pls help should I just get an already built one instead? (I rlly wanna learn how to build tho)
