How does this build look?

I've been officially banned from playing games on my bf's Xbox as I take too long to do anything, so looking to get a PC. A friend has agreed to help do the physical build, but the problem is I have literally no idea what I'm doing with part picking.

For the fans, I'd be looking to put the reverse fan at the bottom on intake, and then the uni fan at the rear on outtake, keeping the 3 built-in fans on the front as intake.

I'd want to be able to run Baldur's Gate 3, Witcher 3, Stardew, etc comfortably. He's trying to get me into CS2 as well, so that's on the cards as well.

This comes out to £1500, and ideally I would like to stay around that cost if possible. Plus, all white build as I am a stereotype 😭😭😭😭
