Using an M7554 KDJ11-D DECserver 550 CPU (in which case it would be an 11/53), or with an M8190 KDJ11-B CPU? Using an M7554 KDJ11-D DECserver 550 CPU is nice in that you get 1.5MB of RAM on board and the two MMJ async ports on the S-handle bracket, but of course it is slower than an M8190 KDJ11-B CPU because it has no cache, no support for adding an FPJ11 FPA, and no support for PMI memory. With an M8190 KDJ11-B CPU you would have to hack up some sort of bracket for the console async port, and for the diagnostic LED display if you wanted that too. If DEC ever made an S-handle console panel for the M8190 KDJ11-B CPU I have never seen one.
