“The physical assembly is inspired by the Cray-1 and Connection Machine supercomputers, also the new Mac Pro. It is 16″ high, with a 12” diameter and 3″ high base. Starting with the original motivation of creating a cooling tower for the 8 Parallella boards (Mac Pro style), the design expanded to also include power transformers, the two NUCs, a gigabit Ethernet switch, an Arduino and LED strips. In the spirit of the Connection Machine (CM-5), there will be 8x Adafruit Neopixel LED strips mounted on the outside of the tower and each with 16 LEDs, which will show the status of the Parallella compute nodes.”
