the form factor is easy to get around

Why did you just ignore everything I wrote, but you still replied to me? No, it isn’t easy to get around. You can use a server to game, but the server mainboards and CPUs expect and work with differently configured memory (registered DIMMs). All the AI infratructure uses that type. You can’t use that memory in a normal PC. Wikipedia reference if you’d like to read about it, but a relevant quote:

[…] the motherboard must match the memory type; as a result, registered memory will not work in a motherboard not designed for it, and vice versa.

You would have to un-solder all the chips and remanufacture new memory modules, and nobody is doing that, especially not at scale. It might be an actual buisness model to do that once the bubble pops, but it isn’t a problem that’s “easy to get around”.>
