If they just got in, didn't break stuff, didn't copy test papers or change grades, didn't victimise anyone - just took some electric and processing power - then they resisted a lot of temptation (or didn't realise quite the power they were holding).

Give the proceeds to charity, repay the electric from their own pockets (eg by doing chores), get them on a course or give them hardware to set up comps they can hack at legally.
