Building a $3000 Pi AI cluster for fun

SMRTR summary

A tech enthusiast built a $3,000 Raspberry Pi cluster using 10 Compute Blades with CM5 modules, totaling 160GB RAM. Despite the investment, benchmarks showed the cluster was 4 times slower than a similarly-priced Framework Desktop setup for high-performance computing, and 25 times slower for AI tasks. The Pi cluster offers slight advantages in energy efficiency and physical node density, but remains impractical for most users except specialized applications like Tor exit relays.
