For training deep learning models and heating my office. Puts out ~850W of heat under full load.
Gradually grew from 2x16GB RAM to 8x16GB and then 7x16GB when a friend needed RAM for his build.
PSU upgraded from 750W -> 1200W to accommodate three video cards for extra CUDA fun.
The name is because I have been using the same Arch Linux installation for 8 years, transplanting it into each of my successive machines. The original machine's hostname was behemoth, and I never felt like changing it.
