Thermaltake AquaBay M1 water reservoir
 

Its well done Thermaltake for this handy combined AquaBay M1 reservoir and flow indicator for small & medium heatsink pipe systems. You can easily use the 10/12mm pipe adapters in the kit. We found that 10mm tubing will fit on the standard smaller fittings. So no need to install the larger ones in the Thermaltake AquaBay M1 kit.
