recall the BA-number of that chassis, but it's basically a BA213 on
its back with the drive bays rearranged. I have one with a VAX-4000/700a in
it, in a seven-foot rack that's impossibly heavy.
You wouldn't have a VAX 4000 700a in a BA213, that is an all Q-Bus
chassis. The upright pedestal chassis for a VAX 4000 700a is a BA440.
The rack mount version of that chassis is the BA441. The system in
Will's photo doesn't look like the standard front face of a BA441.
Here's some BA441 photos:

Ahh, gotcha, BA440. I'd forgotten the distinction with the proc/mem
slots.
Did DEC make an on its back rack mount version of the
BA213?
Yes they did; Sridhar has one. Actually I think he has two, and one
of them came from me. It was pure Qbus all the way across. The one in
Will's photo might be one of those. When Sridhar gets back from his
trip maybe he can compare his with the photo.
