Any altcoin that this home cluster would work with?

I have access to 500 laptops that are still operational.
I want to strip the unit, remove all daughter boards and the LCD to reduce all excess watt usage. Just an open motherboard, wifi, ssd, and battery.
The units at this point range from 3-5 hours of battery with above average end user use so stripped down I hope to get the higher range or more. Charger is a 24 w charger.
My plan is to test the battery life and sort them. Place like life together and put them on a timer. Run on battery for 5 hours, charge full tuen off timer, run on battery - repeat. So less power usage due to battery option.

Mix of i5 and i7 so guessing 2-4 mh with enbedded graphics each.

Are there any coins that something like this would work on?
Current or upcoming?

Kinda making my own legal botnet???
