Last week Shuttle shipped a new SFF gaming machine called the J1 4100G. Today shuttle has announced that it is shipping a workstation version of the J1 along with a G2 7600P SFF workstation.
Presumably, the machines are similar except one uses Intel hardware and the other uses AMD. I will assume the J1 4100P uses Intel hardware since the gaming version does. The machine can be had with Core 2 Duo or Quad processors and NVIDIA Quadro graphics.
