Open-Air Test Bench for Watercooling Builders

The PrimoChill Praxis WetBenchSX Pro Flat Edition is an open-air test bench designed for enthusiasts who frequently swap hardware or test liquid-cooling loops. Its powder-coated steel frame supports both water-cooled and air-cooled components. The flat motherboard layout suits LN2 pots and standard builds alike. It is not for buyers who need an enclosed chassis for dust protection or quiet operation.

Quick Assembly with Modular Brackets

The bench assembles in minutes and features quick-disconnect brackets for the motherboard and radiators that detach in seconds. Modular fan arms can be added for extra airflow when required. Anti-vibration pads for the feet, PSU and radiators are included to reduce noise. Builders who prefer fixed panels or tool-less drive cages will not find those features here.

Radiator Limits and Physical Footprint

The flat configuration provides three mounting positions for radiators up to 480 mm in length. AIO units with 13-inch tube lengths are supported with add-on brackets. The bench measures 338 mm from foot to foot, defining its minimum desk space. Users planning larger radiators or more than four simultaneous mounts should verify fit before purchase.
