Redditor buys 9-GPU mining rig for $35, repurposes for AI

A Reddit user picked up a used mining rig with nine 6GB GPUs for the equivalent of $35 on Avito, Russia's online marketplace. Originally built for cryptocurrency mining, the setup now runs local AI models, handling as many as 30 tokens per second with Qwen3.6-35B-A3B. Performance is held back by outdated hardware and slow PCIe connections, but for the price, it's enough for hobbyist AI experiments.

• Bought for $35 after negotiating on Avito
• Nine P106 mining GPUs with 54GB of VRAM total
• Performance capped at 30+ tokens/second on some models
• Has no SSD; boots from USB stick
• Hardware limitations include low bandwidth and old architecture
