Getting Started with Bitcoin Nodes and Mining

I've got 8 standalone PCs at home connected to a 500MB internet line. They're all i9-9900s with 64GB of RAM and 1TB NVME drives. I'm interested in running a Full Node on one or maybe even all of them, if it's worth it. These machines aren't doing anything else right now. I'm also curious about some basic mining with these PCs, if that's an option. Any suggestions on where to kick things off? What should I keep in mind?

What do you mean by worthwhile? If you mean earning Bitcoin only from running full node, then you should know Bitcoin doesn't reward people who run full node. Full node usually done by people who want better privacy, connect to other nodes or have full blockchain copy for other purpose (such as running self-hosted explorer).
