Mining Rig
A mining rig is a purpose-built computer: a board, a processor, a power supply and several cards, usually on an open frame so the heat has somewhere to go.
The cards do the work. The board only needs enough slots, and the processor can be modest unless you also mine on the CPU. Many builders use risers, short adapter boards that let each card sit away from the motherboard with room to breathe. A small drive or USB stick holds the operating system and the miner.
Power is where most of the planning goes. Add up the draw of every card and the rest of the system, and choose a power supply with real headroom, so it is not running flat out all day. Use the right cables for each card. A cheap splitter or an overloaded connector can melt, and that is a fire risk, not just a crash.
Heat is the second job. Every watt the rig draws ends up as heat in the room. Cards need space between them, the room needs fresh air in and hot air out, and fans and filters need cleaning. A rig that runs cool also lasts longer and holds its speed.
The parts that fail are rarely the cards. Power delivery, risers and dust are what take rigs offline, which is why the power and cooling guides spend more time on cables than on silicon. When a rig keeps restarting, check the power supply and risers before blaming a card.
A common mistake is to build big from the start. Begin with one or two cards, tune them, and watch shares and temperatures for a few days. Add cards one at a time, so a problem is easy to trace to its source.
On the pool, give each rig its own worker name. Your miner page then lists every rig separately, and a rig that drops offline or slows down stands out at once.
