The minicluster, which I presently use for running simulations with OpenFOAM. These are Intel Q6600s with 2gb RAM. It consists of four diskless nodes; they boot with PXE and mount their filesystems from a host machine over NFS. They are mounted on cut-down ATX motherboard trays, tucked up out of the way under my desk in the main area of the bus.

Looking forward into the main area from the kitchen; visible is the spice rack and desk.

See the after picture.
