Thermaltake AquaBay M3 water reservoir
 

As this AquaBay M3 will connect up to just about any pipe size it is universal for all water cooled heatsinks systems on the market and as you can see in our example it would only be a five minute job to install this reservoir. We found that you can fit 10mm tubing to the standard small pipe fittings.
We are going to award this our Editors Top Choice for a water cooled heatsink system reservoir as it is the best we have seen.
