I've written about this elsewhere but I predict there will be a significant secondary market for repurposing parts of datacenter GPUs (for example, RAM chips) by desoldering them and soldering them onto new PCBs that fit PC/consumer use cases.

That might work to some extent with the DDR5 DIMMs connected to the CPUs, but is thoroughly impossible for the HBM DRAM stacks packaged with the GPUs.

I wish there to be an active market like what Gamer's Nexus covered in China:

in the States.

It's all about the cost of labor. In the US you could not find someone capable of soldering BGA chips for a price that makes sense doing.
