0. Dragging an Idle Mini PC into the Game
Today, everyone talks about AI by throwing massive cloud budgets at heavy GPU instances. But my architect instinct always asks a different question:
"Do we really need a massive cloud budget to build a resilient, production-grade enterprise system?"
That's when an idle mini PC collecting dust in my room caught my eye. A modest AMD Ryzen 5500U with DDR4 16GB RAM—the kind of low-spec hardware you easily find on second-hand markets—is now my official server.
On this limited hardware, I'm spinning up Rocky Linux simply because it feels way more comfortable to me than Ubuntu. Without spending a single penny on cloud hosting—well, except for my home electricity bill... wait, anyway—I am kicking off a comprehensive series documenting how to build a production-grade AI Messaging and RAG Platform from scratch.
