While safety should always come first, as long as you don't open the PSU case there's no risk. PC PSUs are well protected against shorts and over/under voltage. Draw too much current and the voltage drops and it switches off.
If you open the case you can get hurt.
The only risk I can see from using an unopened PSU is if someone pokes a metal object through the vents.
