>Were there any PDP11's as small as the DECmate III?

Not really.  The smallest box (available from DEC)
into which one could place a PDP-11 was the Shoebox
(SB-11, or BA11-VA, if I remember correctly) which
was about a foot wide and about 9 inches deep.  It
had a 4slot backplane (4x2, Q, AB side only) and a
power supply.

This was enough to put together a CPU (11/2, KDF11-A,
KDJ11-A), memory, serial lines, bootstrap (MXV11-B),
network card (DEQNA or DELQA) and a disk interface
(RQDX3).  It was not meant for housing the actual
disk.. that would have to be another box.
