Beyond looking fantastically cool, the symmetrical design of the Cray-1 allowed him to design his miniature version in such a way that each individual wedge is made up of the same identical set of 3D printed parts.<\/p>\n<p>In the video after the break, [Kevin] explains some of the variations the design went through. We appreciate his initial goal of making it so you didn\u2019t need any additional hardware to assemble the thing, but in the end you\u2019ll need to pick up some M2.5 standoffs and matching screws if you want to build one yourself. We particularly like how you can hide all the USB power cables inside the lower \u201ccushion\u201d area with the help of some 90-degree cables, leaving the center core open.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From a performance standpoint we know building a homebrew Raspberry Pi cluster doesn\u2019t make a lot of sense, as even a fairly run of the mill desktop x86 machine is sure to run circles around it.
