CleanSpec Lab prepares clean, tested, dependable business desktops, mini PCs, and workstations for reliable second-life use.

Each system is cleaned, configured, updated, and checked before sale, with clear specifications and honest condition notes. Our listings are built around transparency: what you see is what the computer is configured to provide.

Typical preparation includes physical cleaning, Windows installation and activation verification, driver checks, SSD health checks, memory checks, functional testing, and careful packing before shipment.

Select workstation builds may receive additional stability/stress testing, which will be clearly stated in the individual listing.

We also publish technical research, testing results, and engineering documentation that help buyers understand the systems we sell and the improvements we develop.

CleanSpec Lab is based in Michigan and focuses on straightforward, dependable computers with clear specs, honest photos, and careful preparation.
