Sorry, you are missing some vital information: the 68040 cube upgrade board
only plugs into a NeXTbus, i.e., a cube; the NeXTstation has no bus to insert
a 68030 board into; and the NeXTdimension color board (which only plugs into
a cube) does not include a 68040 (which is on the aforementioned 68040 cube
upgrade board).  In short, the NeXTstation and the NeXTstation Color (16-bit)
are low-end non-expandable non-interchangeable non-bus systems, with
correspondingly astoundingly low prices, of course.

Still, if you're knowledgable about busses and power supplies and cooling you
could probably assemble your own NeXT from pieces, or get one of your grad
students to do it :-).

Keep up the creative thinking!

P.S. It's "voila," unless you were addressing a lady reader of this 
newsgroup :-).
