In this video, we put together one of the best budget 1440p gaming PCs you can build right now for under $400! Starting with a used, Grade C Dell Inspiron 3880 that cost just $143 , we replace the proprietary power supply and drop in an AMD Radeon RX 7600 GPU. Paired with the Intel Core i7-10700 and running Bazzite (SteamOS) , this sleeper system delivers incredible 1440p performance in demanding modern games like Cyberpunk 2077, Spider-Man 2, and Red Dead Redemption 2. We also go over the exact adapters you need to make standard PC parts work in these proprietary Dell office cases
