Also, I can’t wait to buy up used RAM for pennys when the bubble pops.

The memory that manufacturers are producing is HBM; they’re transitioning facilities to producing HBM. HBM won’t be in DIMM form factor — you can’t just stick it into the slots on a PC motherboard.

That being said, the hardware in question will probably hit the used market at some point. You might be able to get used Nvidia Blackwells.

Nvidia announces Blackwell Ultra B300 —1.5X faster than B200 with 288GB HBM3e and 15 PFLOPS dense FP4

Those things have 1.4kW TDP. There may be a lot of those things floating around, and if people have enough power and cooling to run those things in their home, maybe they can use repurpose them for something else.
