160 Mac Minis Meticulously Packed in a Rack
From Hack A Day:
[Steve] needed an alternative to the Xserve, since Apple stopped making it. His solution was to stick 160 Mac Minis into a rack. That’s 640 real cores, or 1280 if you count HyperThreading.
Too bad the Xserve was cancelled nearly two-years ago. Nonetheless, very interesting undertaking. Take a minute to read the brief description as to what was required to build this.
