I think $3,495 is ridiculous, but hey that is just me.
Wish I could connect up my other Mac Pro instead of an empty expansion chassis. . . a couple special little magic cards, one cable, and "PRESTO" a Mac Pro as an expansion chassis. . . it would probably be about the same price and could be sold as a useful computer down the road. What can I say, I am bitter. I sold my last expansion chassis for $500 14 months after I bought it new for $2,300, when the Mix systems were superseded by HD and the chassis was no longer supported. . .
