"I heard you have the 60-series," Leo whispered, sliding a crumpled stack of credits across the glass.

"It’ll run anything you dream of," she said, her voice like grinding gears. "But it spent three years mining Borealis-Coin in a sub-arctic server farm. It’s seen things. It’s tired."

Leo pushed through the beaded curtain. The air smelled of ozone, burnt solder, and old coffee. Behind the counter sat Silas, a man who looked like he had been assembled from spare parts found in a RadioShack dumpster.

In the corner, a woman known only as 'The Heatsink' stood over a pile of shimmering green circuits. There were no boxes, no warranties, and certainly no returns. "Does it work?" Leo asked, pointing to a dusty RTX 6090.

"Go to the Docks," Silas grunted, finally looking up. His left eye was a primitive camera lens that whirred as it focused. "Look for a shipping container marked with a faded blue dolphin. It’s where the 'refurbished' units go to die—or to be reborn. The AI miners dump their hardware there when the fans start to scream. It’s a graveyard, kid. But if you can swap a capacitor and don't mind a little silicon scarring, you’ll get 80 teraflops for the price of a sandwich."

Silas didn't look up from a motherboard he was probing. "Retailers will charge you a kidney. The big-box stores want your soul on a monthly subscription. You want the cheapest place?" Leo nodded eagerly.

Leo found the container at midnight. It wasn't a store; it was a digital speakeasy. Hooded gamers and desperate animators bartered in the shadows, trading vintage mechanical keyboards for thermal paste.
