This is a 3-D printable case for the parallella 16-core Desktop Edition computer. The case allows for passive cooling, but be sure to install the required heatsink that comes with the Parallella before hand!
The two types of special connectors allow multiple units to be connected together to form a cluster.
We designed this case for use in my parallel computing class held in Spring 2015. All students in my parallel computing course used the case with their Parallella in the course. We have not encountered any issues with overheating.
The case was co-designed by Suzanne J. Matthews and William ("Frank") Blackmon.
