I was wondering that myself. They didn't include any pic's of the ID plate so we have no idea if it was made before or after TNG filmed..
My initial impression was that they tried to make this look like a desktop PC of that era. While working with the other QBC readers I could see they were designed with function considered over form. This unit appears to have form over function with a focus on aesthetics. Personally I think they failed.
It would look good with some LCARS panels, an animated LCARS screen and some striping. You can even leave the dual knobs on each side.
