I would say nucore is no more or less shock proof than the original computer. Sound level will be about the same as an old computer with good fans. Although some people have power supply/cpu fans that can be really noisy due to failing bearings. Lets say you drop the head from 5 feet (mistake) you would probably sustain the same type of damage with either system. Someone please correct me if I'm wrong here but I do believe hard drive heads retract upon power down to help prevent platter damage from jolts while the power is off. Although you could use solid state storage and you would have no worries.
