Motherboards have had TPM support (built-in/exteral) since like 2017. Are there a bunch of models that don't support a plug-in TPM? I guess the BIOS would probably be the next issue.

The only thing my 2010 desktop can’t do well is run a local LLM.

It can even run diffusion models. I spent a few hundred on a video card for it during the pandemic.

Why should I want to add a TPM to it (assuming it’s even possible)?

fTPM is in the CPU [package], which has been the norm since around that point in time. Motherboard slotted TPMs should be a rarity, now.
