All the PC parts should be compatible on paper but if there is something standing out please let me know. Or if there is a better alternative that I am not aware of, I would love to hear your thoughts. Thanks!
PS. The 6750xt was $379 just yesterday :( Missed my window.
Besides what others have pointed out already, the peripherals are decent but if you’re going all out then I highly recommend getting a mechanical keyboard. Once you try one you never go back, and they last much longer. I hesitate to suggest anything since it’s such a customizable thing, but the Logitech G413 is >$50 if you’re looking for something around the same price point.
