10-1/4 x 7 x 8-1/8 = my Shuttle 9-7/8 x 7-3/4 x 7-3/4 = my Cube Maybe they sold you a very large Shuttle, Ton, or you have a rather unusual undersized Cube. I'm not bothering converting the external measurements into volume, but I doubt there would be very much difference if I did. The real difference is that the Cube is standing up, less footprint but higher shelf space needed (esp. for CD/DVD feeding), and the Shuttle is resting on its length, it's shorter but deeper shelf space required (esp. for wires going to the back).
