Liquid Cooling Reservoirs

The Reservoir is the part of the loop that feeds fluid to your pump. There are loads of options so choose one that is designed for use with your pump or use a reservoir that fits in your case. 

The most popular reservoir designs are:

Tube Reservoir - A tube reservoir usually provides a lot of options for flow directions and is useful for putting a lot of fluid into a high flow pump.

Bay Reservoir - A bay reservoir provides easy mounting and filling opportunities as it sits where your optical drives go in your system. The benefit of a bay res is that you can see your coolant at the front of your system which some people like

Pump Combo Reservoir - Combination reservoirs are designed to fit directly onto your pump and often provide excellent flow into your pump thus giving the best performance level. There are a lot of res combos available that are specific to certain pumps so check your pump model for res availability.
