Upgrading a Prebuilt PC

kernmatt

Hi so I was planning on building my first pc but getting parts during these times just became too frustrating. Today I just bought this prebuilt pc https://www.amazon.com/gp/product/B08H4Q7546/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1

I cant find much info on this pc but i already own a brand new ROG STRIX B550-F and would like to put it in this rig so i have more memory slots but I don't know how to tell if it is compatible with the case.
I also have a 750W psu and RAM sticks that are brand new that I would like to put in this. 
I'd really appreciate any help I can get
