Refers to the art of arranging the cables inside one's computer case in a very tightly-integrated, neat, airflow-friendly manner. (This is especially important for those with windows in their rigs.) Derived from the Japanese "origami", the art of paper folding. Cablegami not only involves folding and twisting of cables, but, like origami, it is maddeningly difficult to do well.
"Man, did you see the cablegami that guy with the acrylic case pulled off?"
"Yeah, for a second I thought he had a wireless hard drive."
