This is what I have, but I must say a few things...
Anything in the list below without a price on it is currently out of stock on amazon, so use the given link to see if it is in stock or not. Secondly, I couldn’t find a good graphics card on amazon, so you’ll either have to make an exception on the store you’re buy it from or not have a system (because the Ryzen series needs a dedicated gpu). The system assuming I posted a complete setup without peripherals would be around your budget.
