What prebuilt should I buy?

I am looking to buy a prebuilt as my first pc. My budget is 1200$ I want it to be able to run AAA games at a high framerate. I don't care that much about graphics (I only have a 1080p monitor). The things I care about the most are High framerate (performance settings), good storage and good ram.

I don't know much about pcs so sorry in advance.

Also I am coming from Xbox Series S
