The particular scheme that Thad Floryan suggested and which I was advocating
requires that the connector be mounted perpendicular to the board (rather than,
say, parallel to the board at an edge) and that places be provided on the board
for screwing in standoff pegs -- i.e., the board must be designed with the
method of mounting the connector in mind.  This still seems to me to be the
cleanest method for installing the board.

You are right that there is very little room in the box, but if I recall
correctly from the last time I looked inside there ought to be just enough
space to mount the board against the back "wall" as Thad suggested.  I'm not
certain of this -- the metal "fingers" that ground the back of the disk drive
enclosure might get in the way.  (This space is the same on both 3b1's and
7300's.)  It can get pretty hot where I keep my 3b1 and I am loath to remove
the second fan.
