That case is the 'Maddox layout'.

The 'original' P3 case was a black desktop case sold by Maplin.
Only four P3s were produced by myself in that case, such as this one...

Note the lack of mode keys and LEDs, and data knob - the earliest units were
all retrofitted with those later.
Only one original case survives unmodified, though non-functional.
 
Later pre-production units used a very similar Hammond case, like this...

The Maddox layout (so called because Paul Maddox came up with it) used a
different Hammond case, which is narrower but deeper - hence the relocation
of the display and keypad.
The main advantage of that case was that it came with wooden end cheeks ;-)
I built a couple of those as special orders, and a few other cases in that
style were made by Steve Thomas, when he was doing his DIY CNC work.
I don't really get on with that layout as the buttons are not where I
expect.

I built a number of pre-production P3s using Schaeffer panels in 19" rack
mount form, such as this one...

A few tweaks later, I ended up with this design...

...which didn't change much before going into production.

There were also a couple of other variations, such as Gert's Big One...

Check out the standard PLED display on that one for an idea of scale.

And the super-compact 'hand-baggage' P3...

Is this what they mean by a 'case history' ?
