This is the full archive of articles published on TechFuel HQ — every piece in one place, sorted newest first. The site’s focus is hands-on infrastructure for self-hosters and budget PC builders: Proxmox, TrueNAS, and Unraid tradeoffs; mini PCs and small-form-factor server builds; 2.5GbE and 10GbE networking on a budget; self-hosted apps that actually replace SaaS; and repurposing older gaming hardware as servers.
About this section
Each article links its sources inline and carries a Last-Verified date. Hardware claims that depend on a first-person measurement are backed by the corresponding artifact (photo, screenshot, captured terminal output); vendor specs and public benchmarks are cited with links to the source page. The full editorial standard lives on the methodology page.
If you’re new to the site, the start-here picks on the homepage cover the biggest decisions. For a focused entry point pick the relevant section: Homelab, PC Builds, GPU Reviews, Networking, or Tutorials.
