Very cool. So what was the original cost? hp.museum.net lists a $22000
figure without configuration specifics.

This page says 90,500$ for a 2000A system, although that seems like a
lot for the 1969 version:

Not much core in a 2116A to be running a timeshared system.
Can't see what the unit under the CPU is - memory expander? disc
controller?

What is in the gas tank ? That picture
scares me. That looks like more
Manhattan Project surplus than a computer. Very cool though.

Not very often that discs or drums are seen for the early HP 211x
machines.
One would need the software to make it an HP 2000 system, or one can
hope it's still on disc.

That is where the brain is stored, suspended in white blood...It was
originally transparent, but HP changed to an opaque enclosure because it
drawn too much attention :)

There's a speed dial on the front that goes all the way up to 11.

The gas bottle by the hard drive said "Helium" on it - very weird. It seems
unlikely that the hard drive is Helium-tight. For cooling?

Pretty much. Helium has been used with magnetic drums at least since
the 1950s. It has a relatively high heat transfer coefficient and so
reduces localized heating between the drum and stationary heads.

The original hard disk on the Air Force AN/FYQ-93 (based on a Hughes
H5118ME central computer and four HMP-1116 peripheral processors) used a
similar setup. One of the preventive maintenance tasks was to
check the pressure and pump function.
