Mining Rig

In GPU mining, a rig is an open-air frame with a motherboard, minimal CPU/RAM, riser cables, and four to twelve graphics cards sharing one or two power supplies. The open design prioritises airflow and serviceability over aesthetics.

Rig economics reward standardisation: identical cards, one OS image (HiveOS, mmpOS and similar), centralised monitoring, and per-card power tuning. The term is also used loosely for ASICs, though those are sealed appliances rather than assembled machines.
