Plus lots of cables, cage nuts and screws, a manual winch hoist, and emergency supplies of Mountain Dew (the original, none of the newfangled stuff).
In total the cluster currently has 272 CPU cores, 528GB of memory and 9TB of RAID5 hard disk storage.
At the moment 256 CPU cores are on-line due to defective mainboards in two of the NumberSmasher nodes.
