Why I'm traveling to India to build a dual-RTX 3090 rig for local LLMs

A blogger shared a cross-border deployment plan and cost analysis for building a local GPU server to run Qwen-3.8:
Hardware Selection:
- GPU: 2× used RTX 3090 (24GB) are cheaper in India, with room for future upgrades.
- CPU/RAM: Ryzen 5600 + AM4 + 64GB DDR4 is cheaper to buy in Germany.
- PSU/Mobo: Sized for dual GPUs to enable easy future scaling.
Operational Costs: Electricity costs in India are significantly lower than in Germany, even after accounting for air conditioning.
Network & Remote Management:
- Uses encrypted WireGuard/Tailscale tunnels for remote access.
- Tested upload speeds from India are acceptable; network is not the main hurdle.
- Uses a 2013 Mac (Linux) as the remote management box.
- Plans to add PiKVM + UPS to debug the rig from 6,500 km away.
