Zotero + WebDAV for me too (I use the Caddy WebDAV module).

One thing I would do differently is setup LDAP and OIDC so you can use the same authentication credentials for different apps (at least the ones that support them). I use LLDAP and Authelia for this purpose.

I found a VRAM calculator for LLMs here: https://huggingface.co/spaces/NyxKrage/LLM-Model-VRAM-Calculator

Wow it seems like for 128K context size you do need a lot of VRAM (~55 GB). Qwen 72B will take up ~39 GB so you would either need 4x 24GB Nvidia cards or the Mac Pro 192 GB RAM. Probably the cheapest option would be to deploy GPU instances on a service like Runpod. I think you would have to do a lot of processing before you get to the breakeven point of your own machine.

The context cache doesn’t take up too much memory compared to the model. The main benefit of having a lot of VRAM is that you can run larger models. I think you’re better off buying a 24 GB Nvidia card from a cost and performance standpoint.
