Building a new PC doesn't require a premium budget, but finding a case that balances airflow, cable management, and modularity at a fair price is tough. Amazon is currently selling the white CORSAIR 4000D RS ARGB PC Tower for just $75. That's a 40% discount off its regular $125 price, making it the lowest price we've seen for this chassis. If you're planning a new PC build, you'll want to take advantage of this deal.
