Need help!

Hi guys! I'm located in Australia and I was wondering if I could get some help with selecting a prebuilt pc to buy, my budget tops out at around $2500 and I would prefer a white one. I'd be looking to play a variety of games like Elden Ring or Baldur's gate 3 as well as multiplayer shooters like overwatch or marvel rivals. I've been looking at websites like aftershock or nebula but I'm a little overwhelmed by all the options and the specs. Any help would be super appreciated! :)
