DIY Pi cluster claims a $2,500 path around $15,000 enterprise servers

A post argues that enterprise servers are overpriced and that local-first clusters can beat cloud costs.
- The build uses 8–12 Raspberry Pi CM4 nodes plus Seagate IronWolf HDDs in a custom 1U/2U chassis with integrated switching.
- Claimed economics: about $2,500 total hardware cost versus $15,000+ for a traditional server, plus $500/month in cloud overhead.
- The system reportedly draws under 100W at full load and pays for itself in about 6 months by avoiding egress and subscription costs.
