I created this 3D-printed case for an 8-node cluster of Nvidia Jetson-TK1 embedded Linux boards so that I can learn embedded Linux, CUDA, MPI, and other high performance computing technologies.  Each of the 7 vertical nodes has a Jetson board and a 2.5" SSD. The horizontal 'Master' node adds an additional Gig Ethernet port via the mini-pcie socket (to connect to a development PC), a powered USB3 4-port hub, and a realtime-clock PCB. It is connected to the 10" monitor via HDMI. An 8-port gigabit switch PCB crammed into the bottom case above the 300 watt power supply connects all the nodes together. All I need to develop CUDA /Cluster apps is plug the unit into an AC wall socket. You will need a 3D printer capable of printing 225mm x 130mm parts ( ~9" by 6" bed).I have included .STEP format design files of all parts to facilitate modifications.I updated Files and Documentation on March 15, 2015
