Really hard case like that are sometimes marketed as a "vault". I see some Hori vault cases, but they are colorful, not understated like the one in your picture. I also see an "aluminium" case by hori. I don't know how similar the construction may be. https://www.amazon.com/HORI-Alumi-Mario-Nintendo-Switch-2/dp/B0GWNFQT7B/ . (I only searched amazon)
