You dont state if its on a server or off line, if on a server just take a sec to make sure there is no chance of any form of spillage, (NOT ANY CHANCE AT ALL), consider what could happen if xx storage gets full or if the power stops, I know in 99% of cases it fine, but really you would be shocked to find out how many players that should know better get caught out, & if you have a buddy ask to swing by & check now n then while your off line, remember too that if there is ever an issue the admin will just delete any & all offending machines, for warned for armed.
Personally I turn my systems off when I log out.
