At $190 it is expensive for a case. But if you want small and fanless....Streacom makes 65w capable Fanless enclosures, but they are a fair bit bigger. In fanless, size and power dissipation are going to be inversely related.
But I too would trade bigger size to be able to use a Ryzen 2200G.

It's still small, and you CPU options increase a LOT.
