   Not so much a series...but the BA23 and BA123 do share some  
similarities.  The internal DEC prototypes of the BA123 ("woody  
boxes") were actually built from mostly BA23 parts, including the  
backplane and power supply.  The production BA123 was very different.

   This is correct...they're held on by strange snap connectors that  
work similarly to velcro.  It might be quite tough to remove; just  
give it a little force and it will be fine.  Be advised, however,  
that there are open rectangular handles underneath the front and rear  
that are designed to be used as lifting points.  They're actually a  
part of the main outer case, not the front or rear covers...but If  
you just reach into the hole in the bottom of the front or rear and  
start pulling, you'll be pulling against those handles and you won't  
get anywhere.  You need to pull on the body of the front and rear  
covers.  You'll see how all that works when you get one of the covers  
off and look at the main plastic case.
