Their is no specific size for a computer and the weight of a computer is not dependant on windows 8. The weight of a computer depends on the weight of its components. The heaviest component is most likely the power supply. The next heavy component is would a hard drive. Either of these can be several pounds. A computer can have more than one power supply for backup and several hard drives. The case with all the computer parts can also be very heavy depending on the material used to make it.
Almost all the parts in a computer are subject to being replaced with much lighter, but much more expensive, components and can certainly reduce the weight of a computer to much less than one pound.
