K80, Is it possible to still use these cards?

Hello, I am trying to utilize an offline ML setup for home/education purposes. I have two K80’s that I was hoping to use for this if it is still feasible.
If it is, what compatible board should I be looking at?
Any feedback including suggested builds for LLM’s would be greatly appreciated. Other than the two K80’s and a personal laptop with a NVIDIA 1650. I am starting from scratch on this build.
