Answer : Can not Hibernate

gyurika--As mentioned earlier, there really is little difference between Hibernate and Standby for a desktop.  The main advantage to Hibernate is for laptops where you can conserve battery power.  
However, I am sure there are others who feel differently.  And I cannot argue with your decision.
