The NeXTcube (1988-1995), history and design

The NeXTCube was a workstation manufactured between 1988 and 1995 by NeXT, the company founded by Steve Jobs after leaving Apple in 1985, also famous for its iconic cube-shaped black chassis.

Called simply NeXT Computer, the first version of the machine was also the first computer released by NeXT. With it, Jobs wanted to demonstrate what his visionary approach could achieve without the interference of Apple’s shareholders.
Therefore, he created a revolutionary, high-end workstation with a great graphical interface, a solid operating system, powerful hardware, and, last but not the least, an iconic design.

Aimed at professional users and institutions, the computer was originally equipped with a 25MHz Motorola 68030 CPU (then upgraded to the 68040), up to 64MB of RAM (128 in the NeXTcube Turbo), and a rather unconventional 256MB magneto-optical drive. The operating system was the NeXTSTEP, a variant of Unix that would later serve as a base for the Mac OS X.

Designed by Frog Design, a firm founded by German designer Hartmut Esslinger in 1969, the famous black painted magnesium-alloy chassis of the workstation is an almost perfect one-foot cube. Almost, because the case is actually about one millimeter shorter than it should be to have all sides exactly one foot (or 12 inches, or 30,5 centimeters) long. In the film Jobs (2015), the fictional Steve Jobs says this was intentional because: “To the human eye a perfect cube doesn’t look like a cube”. Yet, whether this small difference in length is really by design or is just due to manufacturing tolerances has never been clarified.

Since it was (and still is) very difficult to manufacture a die-cast enclosure with 90° angles (it’s much easier and cheaper to have slightly wider angles, since this facilitate the extraction from the mold), the sides of the case of the NeXTcube had to be made separately and then welded together.
The case was made in an alloy composed of a large percentage of magnesium, to which other materials were added to prevent ignition (magnesium is a highly inflammable metal), and manufactured by NeXT in a highly automated factory located next to the company’s design office in order to keep control over the manufacturing process.
The enclosure was painted black, both externally and internally, with non-toxic water-soluble paint, thus obtaining that “black monolith” look that contributed to making the NeXTcube so famous.

Also important was the company’s logo and visual identity that marked the computer’s front; designed by the famous American graphic designer Paul Rand, it featured a stylized cube (again), tilted by 28 degrees, with the word NeXT written in high-contrast colors (vermilion, cerise, green, and yellow) against black.

“What is needed is finding a meaningful device, some idea that reinforces the memorability of the company name. A black cube can be such a device because it has visual impact, and is easy to remember.“  Paul Rand about the NeXT logo design.

Overall, three aesthetically similar versions of the workstation were made, the NeXT Computer (1988-1991), the NeXTcube (1990-1993), and the NeXTcube Turbo (1992-1995).

Though not a great commercial success, mainly due to its high price, the computer was very appreciated by professionals and researchers, such as the inventor of the World Wide Web, Tim Berners-Lee, which once called the NeXTCube “the actually usable computer”.
Like other projects developed by NeXT, “The Cube” was also a source of inspiration for various products made by Apple after Jobs’ return to Cupertino in 1997, including the Power Mac G4 Cube, of course.
