Re: Power off, cons?
You fail to mention who paid for the computer and who pays for electricity.
If he owns any share of that computer and/or you don't pay any part of the electric bill you gotta suck it up until you move out. Power it off, or put it in hibernate.
As for damage, odds are only the PSU will get hurt from this. If this has been going on for a while then you shouldn't have much to worry about as signs of damage should be there by now.
