Mining frame
Also called: chassis, mining rig frame, open-air frame
A mining frame is an open frame that holds a GPU rig's motherboard, power supply and graphics cards, with plenty of space between them.
The mining frame, or chassis, is the structure of a GPU mining rig. Unlike a closed PC case, it is an open frame, usually made of metal, on which you mount the motherboard, one or more power supplies and a row of graphics cards. The cards are connected to the motherboard with PCIe risers, which lets you space them apart from one another.
This spacing is key. Several graphics cards packed into a closed case bounce their heat off each other and run very hot. On an open frame, each card can breathe, and case fans can blow a shared airflow across the whole row. The result: lower temperatures, fans spinning more slowly and cards that last longer.
To choose one, start from the number of cards you want, often 6 to 8, sometimes up to 12, and check that it matches the number of PCIe slots on the motherboard. Look at the spacing between slots, which must suit the thickness of your cards, the room provided for power supplies, the fan mounts and how sturdy the whole thing is. An open frame remains exposed to dust: install it in a clean, ventilated room and clean it regularly.
We offer open frames for 6 to 12 GPUs, with or without fans, as well as complete kits for building a rig.
