After four motherboard replacements, this machine is again operational. It
is an 18-core hyperthreaded (36 thread) machine with 256GB of RAM, the CPU is overclocked at 4.9Ghz. In this configuration it can consume up to 540 watts if running full-tilt and finding a motherboard that could provide the required power was difficult. The Asrock actually melted the solder connections at the CPU socket.

All of these services except the shell server are free, the shell server runs $8/month for a standard account of $84/year.
