honestly I'd also watch some gamernexus videos on prebuilts. I dont trust most prebuilts airflow designs. pcpartpicker.com is a good website to use when building (DIY) your PC. what do you plan to use the PC for? if gaming then building around a 5800X3D is a good option (AMD fanboy here).
I'm not up to speed on intel's newest stuff since i dont follow team blue too often anymore but i do know the 13 series is a good option as well.

its overkill but ehh its under budget. there are probably areas for improvement in this build and you'll need case fans.
you didn't mention a budget. i own a 6900XT. really good card for the price point IMO. would recommend a whole new build around DDR4/DDR5. intel or AMD, either is a good option nowadays. post your budget and someone here could help you.
