I'm trying to avoid having to throw away my decklink mini monitor 4k that I used in my old PC build. It's a PCIe gen 2 4-lane card.

To replace this card with something new of similar function that uses external ports, I have to either buy something quite a bit worse in terms of function for a little bit more than my current PCIe version currently costs, or something equivalent in function for way, way more than the 4k decklink costs.

I figured best bet would be to just get a PCIe enclosure to keep using my old card with the new laptop but the costs of those enclosures are STAGGERING, just unbelievably high. The cheapest I could find is 2nd hand and so old it uses TB2 ports. I thought that might be okay with thunderbolt adaptors for modern connectors but it occurs to me that Apple Silicon driver support could be an issue. Any idea if it would even work?
