Three things you should keep in mind regarding those numbers:
1. They're worst case numbers, as in the hard drive being mounted perpendicular to the impact force. Some OEM crapbox PCs may have spinning rust mounted to the front of the case directly in a vertical orientation, but most PCs have them mounted horizontally and many use shock absorbing rubber bushings.
2. As noted, your numbers also assume an inelastic collision. Almost all PC cases have a plastic front, and all robo-vacs I'm aware of have the same.
3. The absolute peak potential impact force is significantly less than a single accidental kick or kid/pet running in to it.
If you're really concerned about impact, you should get your PC off the floor. That said, I'd happily frisbee a Roomba at my PC and not be concerned for anything other than the front panel of the case itself.
