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

in the States.
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.
