Crypto PC Rig
This Crypto PC Rig is an open-frame mining build engineered for stable 24/7 operation, powered by three efficient RTX 3070 GPUs and tuned for the best possible profitability per watt.

Project story
This crypto rig was assembled for a customer who wanted a reliable mining machine that runs day and night without babysitting, high temperatures or hidden hardware compromises.
Planning started with the choice of the right frame, motherboard and PSU — the parts that decide whether a mining rig lives for years or dies in a few months of heavy load.
GPUs, motherboard, risers and other core parts were selected primarily from Alza.sk and other trusted retailers after comparing hashrate, power consumption, warranty and long-term availability.
Every GPU was carefully undervolted and its power limit tuned so the rig delivers a stable hashrate at the lowest possible wattage, protecting both profitability and lifespan.
The open-frame layout was configured for maximum airflow, spaced risers keep the cards cool and the whole rig is monitored remotely so the owner sees hashrate and temperatures at any time.
Hardware
Low-power CPU — perfect for a mining node that offloads work to the GPUs.
Three RTX 3070 cards tuned for the best hashrate-per-watt ratio.
Dedicated mining board with plenty of PCIe slots for stable multi-GPU setups.
High-efficiency 80+ Gold PSU sized for 24/7 mining loads.
Open-air layout with spaced risers keeping every GPU cool.
Sturdy open-frame chassis designed for continuous heavy operation.
Purpose-built mining OS with remote monitoring and fleet management.
