Home Lab Roadmap
A long-term plan for purpose-built, always-on infrastructure: an enterprise server and rack, NAS with RAID, TrueNAS or Unraid, containers, Plex, virtualisation, and future off-grid solar integration. The design responds to Sri Lankan electricity costs by prioritising lower power use, storage resilience, and continuous availability over a permanently running workstation.
