The gpus were stored on homemade racks made from aluminium and wood, spaced for proper airflow but allowing for many cards on one motherboard. Server power supplies (on the left) were used for their higher efficiency ratings and power capacities.
Copper plates and new thermal pads on the memory allowed for cooler and safer operation of 3080s and 3090s
Space-efficient homemade mining rigs allow for optimal cooling and airflow, increasing sound, performance, and power efficiency.
My initial mining setup for optimal space efficiency, all powered on one power distribution unit (PDU)
A water-cooled core and copper plates on the power delivery make GPUs more power efficient
