Obviously case is pretty clearly a different casting; in addition to the different keyboard opening(s)) details like the bezel trim and the braces that hold the lid up are different. Also, while it looks like the gross layout of the chips on the motherboards is similar the typeface looks different and some of the positions of things like resistors, etc, don't match.

From what I can see, the board looks like the one in my ITT 2020. The layout is the same overall as a Europlus with detail differences (silkscreen and pin connectors). The power supply looks like mine which has a captive mains lead (no IEC mains connector). The RAM chips on my board all have gold paper ITT labels.

The keyboard is interesting and probably explains the case transplant. ITT used at least two case designs. The early one was a copy of the Europlus in silver. It has a smooth texture and minor dimensions differ (thickness, small radii). There are two rubber stamp marks on my lid: a date (illegible) and P AMCO, which I presume to mean Passed by AMCO (an old UK plastics firm). A later case had squarer corners and the rear back panel is cut away (ie no separate cut outs for ribbon cables).

ITT offered their own Disk ][s. Mine is incomplete, missing the lid. And yes, the ITT 2020 was a "clone", in the fashion of Power Computing Macs. It was fully licensed with its own version of the Apple II red book (on A4 paper):
