In general, the "HDD" and "Power" LEDs are bare LEDs without current limiting resistors, meaning that the necessary current limiting will be provided by a series resistor on the mobo.
Your case LEDs, on the other hand, being designed to be powered by a power supply connector (I'm guessing it's going to be the 5 volt half of a Molex drive connector), will have their own current limiting resistor[s]. If you connect the "art" LEDs to the HDD drive connector it should cause no damage, but you may be quite disappointed in the level of brightness you achieve. If you want to play around with some kind of transistor drive circuit you could get full brightness, but that would involve knowing whether the drive to the HDD LED is "active high" or "active low" and would also involve having some knowledge on how to design a simple transistor drive circuit.
