Both the PDT-11/110 and PDT-11/130 are built into VT100 cases, so
that is what they are the size of.
The PDT-11/150 is a separate box which is an 8" floppy drive wide,
about 12" high and about 14" deep.

You forgot memory...
And the box exists, it is a BA11-VA (the Shoebox).

But that is a 4 x 4 backplane... so it is 19" wide (with the
attached power supply).
