I cannot find any guides for these and I've never done this before.
I want to set them up to mine altcoins like bitcoin cash or peercoin.
I would like to know how to setup to mine with a pool as well as on my own.

PLEASE DO NOT WASTE TIME TELLING ME IT'S NOT WORTH IT, I KNOW. I'm trying to learn. The profit is irrelevant.

-I have access to free electricity and a couple dozen Windows pc units. I'll post the specs at the end.
-What I want to know is, what is the easiest or most profitable cryptocurrency to mine?
-I do not have any money to buy any extra equipment or do any upgrades.
-Please point me to a guide on how to mine whatever you suggest.
SPECS.
