My VAX 6000 is no longer here, so I have to go on
memory. Pretty much all
there is in a standard 6000 is a row of PSUs at the top, a row with the
VAXBI and XMI busses and - right at the bottom - a converter/coditioner
that takes the incoming power feed and presents it to the rest of the box.
There is a large gap with plenty of air in it. About the only thing you could
use it for was a late-breaking internal storage addon. Every 6000 I've
seen had external storage (mostly via CI, since that's what big customers
were expected to do).
Gunther Schadow has a nice web page with extensive photos of VAX 6420s:

Internally it cannot have been much wider that
19" so I would guess that the
rack-mount version would be about the same but without the large wad
of air :-)
The physical config on these is /entirely/ different. Here are the pics
These systems are basically the PSU, fans,
and the XMI. The small
amount of space to the right of the XMI cage seems to be used as a
storage area for the anti-static strap. It's a little too narrow for
a BI bus card cage.
