The BFG GeForce GTX 280 H2OC card fitted with barbs to match the hose size. BFG not only includes its own barbs and clamps, but also replaces the PCI bracket to make the whole thing completely single slot.
The components were laid out in the case to evaluate how best to connect everything up and the correct size barbs were also fitted to the reservoir as well.
The reservoir was then installed, as was the radiator in the pre-fitted holes on the Omega, above it. The OCZ Flex II memory with its provided tubing cut and fitted to the 4-way manifold, ready to be connected to the next component in the loop.
We finally got ready to turn it on and... disappointment. There was absolutely no pressure in the system and we couldn't get it to fill all of the tubes. One thing we noticed was that the OCZ 4-way manifold was incredibly restrictive to flow and the tiny tubes kinked very easily indeed when compared to the much thicker tubing they connected to. This meant that the wider tubing needed to be longer in order to bend more easily.
We decided that the BFG GeForce GTX 280 H2OC card was just too much for it and removed it from the loop - after all, a pump and single radiator can easily handle a northbridge and memory. We also arranged it so the northbridge was first in the loop this time, so the memory wasn't overly restrictive. However we found the pump again failed to fill the tubes and more obviously this time it failed to create any pressure what-so-ever, even after we tried tilting the whole system or filling the reservoir a little higher.
So we took it all apart and tested the pump on its own - we even removed the dodgy connector and wired it up manually. This "1.2l head" gave us all of 10cm - that's one broken pump!
