This is more on the upper tier of your price range. You can drop the CPU down to a Ryzen 3600 or the GPU down to a GTX 1650 Super or RX 5500XT
I gave you a very fast SSD for editing files on, as well as a good GPU to help with rendering/previewing .
I didnt include an OS incase you already have a copy. If not you can always run Windows without a license or buy a cheap License Key online.
