So I have two laptops. Both run Linux Mint.

I need Laptop 1 to work with.

Laptop 2 is an unrepairable POS that starts having a little trouble with keyboard and hinges but works nicely otherwise and has a nice large 1TB disc and a GPU. I want to bury L2 in a shelf(*) and save videos and music on it to access from L1.

I would also like to play with Stable Diffusion, accessing it from L1. Can I do that?

(*) Bonus points for ideas about how to have L2 do other useful things when I don’t use it and install it as grow tent heating instead of just have it sit in a corner.
