Singularity Computers Protium 3.0 Reservoir 200mm – Acetal Black

The SC Protium Reservoir 200mm comes in three different colors/materials, Clear Acrylic with Black or Silver metal and Black Acetal with Black Metal. It uses a retention ring design instead of threaded caps. This allows for 360-degree rotation of the reservoir caps, and it is far more durable than caps which thread onto the inside of the reservoir tube. The retention rings built from CNC machined anodized aluminum and do not contact the fluid.
The reservoir has 4 ports with a dual port cap on each end. The caps have a recessed top to catch any fluid in the case of an overflow and this also acts as a mounting position for the integrated ARGB/DRGB LEDs. The LEDs are on a custom PCB which positions them to make the entire reservoir glow, and the coolant inside.
