Modular open-air test bench

The PrimoChill Praxis Wetbench is a powdercoated steel open-air frame designed for custom watercooling loops and air-cooled builds. Its slanted motherboard posture and modular layout give unrestricted access to components during frequent hardware swaps. Builders who need a permanent enclosed chassis with dust filters and noise damping should look elsewhere.

Motherboard compatibility range

The bench accepts mITX, mATX, ATX and eATX boards, covering the common form factors used in test and showcase systems. Proprietary or oversized server boards that fall outside these standards will not fit the mounting pattern.

Quick-release tray and GPU bracket

A removable tray allows the motherboard and attached hardware to be lifted out in seconds for rapid reconfiguration. The included GPU bracket raises the overall height to 440mm; without it the frame stands at 330mm. Two 5.25in drive bays are provided for optical drives or reservoir mounting.

Questions about this item

How does the 461.8 mm foot-to-foot length affect component layout on the Praxis Wetbench?

The 461.8 mm span gives plenty of room for eATX boards and long graphics cards while keeping the open frame compact enough for a standard bench.

What does the open-air concept mean for cooling limits in practice?

With no side panels to restrict airflow, CPU and GPU temperatures stay close to ambient, but dust settles faster and there is no acoustic dampening.

What clearance does the 483 mm front-to-back depth provide for radiators or long cards?

The 483 mm depth accommodates dual 5.25 in drive bays and leaves generous space for thick radiators or extended-length GPUs without crowding the motherboard tray.
