Nope, different machines. One has a number stamped on the
casing near the fan cutout, which the other doesn't, and the QA
stickers to the rear of the STB ROM are different. It's interesting
that all the ones I've seen so far have the fan cutout but no fan.
One would think it'd be needed with the 68040 in there with no
heatsink. Are yours boxed? Mine is, but somewhere along the way the
Apple ID stickers were removed from the bottom of the unit.
