Good on you to pass this gear on. It's older, but I just found out that apparently proxmox 8 even works on old core duos so these are still good for learning.I have several really old Dell servers I am gonna bin but if anyone wants them they are welcome to them.
They are mostly generation 9 servers 1950/2950's etc but one is a generation 10 R905, there is also quite a lot of ecc ddr2 between them some fb and some not.
If anyone is interested I can put together a list and check what works and is complete, but I am guess they are too old for anyone to have an interest.
I am in Devon UK for any collections.
let me know if anyone wants a list.
