Those are 'covers' that slide back and forth over the cards (sliding 
plexiglass doors;).

The left-most backplane is the KA780 (CPU), the next one to the right is 
memory - it appears to have 8 memory boards.  The next two card cages 
are DW780s or RH780s (unibus or massbus interface boxes).

There's an RX01 on the right, bottom (the silver colored box).  The drive 
faces upwards (only a single-drive not a double-drive), and swings out 
of the front of the VAX.

This guy can't spell and has no idea (imho) what these things are worth.  
The last 11/780 "untested" I saw on ebay went for $70ish to Dave 
McGuire, I picked one up from the same seller for $350ish which included 
a Data General Eclipse MV1400, Sun 3/180, DEC Rainbow, a pile of fujitsu 
14" SMD 800-900MB HDDs, an 11/750, and some other stuff I can't remember 
anymore (including a bunch of BA11s with UNIBUS cards and one UNIBUS 
SCSI card in it ;).   A bunch of it wasn't 100% working, but the stuff 
I've fixed so far hasn't been difficult to repair.

I'd say a price of $100-$200 depending on how much you really want it is 
a better price, considering that it may not be functional.

If you have more questions, I can tell you what mine looks like for 
reference.
