Northbridge Block - 8mm / 1/3"

[paulspiteri]

Hi
I'm looking for a northbridge water block compatible with my new zalman reserator. I believe it uses 8mm connectors & pipes, which i think is 1/3" in old money.
Any recommendation of what blocks are suitable? I've only found the innovatek stuff which seems right but can't find any places in-stock, here in UK.

Thanks..
