Hello everyone this is my first post and i really hope to get replied to soon

Well as you know the heading is what to mine with 20 cpus (no gpus)
well the The thing is i ve managed to ge access to 20 cpu most of them are intel i3 and unfortunately windows xp (8 of them). But i dont pay any electricity so i was wondering which coins to mine whether i should mine different coins or one specific coin

And which script is the best for cpu mining would really help me out.
I dont intend to make a huge profit. But just wanted to maximize my profit to create a nice faucet later on I might hold the coins for a year or 2 so whatever coin which would "go to the moon" in that time tell me about it
Thank you

P.S
Those CPUs are not mine i dont need to worry about cooling i get no loss even if they explode. They belong to a cybercafe and they r on 18hrs a day so y waste it? also i need to know whether to use hoDL algorithm or cryptonite or any other better scrypt/coin
