Agreed. Might not be identical in size, but same style for sure.

Not so sure about this one. I disagree on the drives vs CPUs, at least
in the case of the external TK50s. I have several of these 'Leprechaun'
boxes (most with dead PSUs, but that's another story). They are only
wide enough to take a slab PSU mounted up on edge next to a 5.25" device
on a BA-23-type skid, with up to 3 ports on the back, directly behind
the drive. One or two are external TK50s, one is an external RX50 unit
for my RUX50 controller (purchased new for an 11/750 by the previous

The DECmate III(+)/MicroVAX 2000 case has a boxier PSU and is wider as a
result, in addition to taller, since the main board is above the drive,
making the the ports stick out over a cutout on the back of the case
and face the floor, not the wall.

I will agree that these are all of similar 'shoebox' proportions, not
'desktop' proportions like the DECmate II or PRO, but there are enough
differences that I hesitate to call them the same style as each other.
