Sadly theres very few pump brands in New Zealand - Hydors (sp?) are really hard to come buy, pretty much eheim is the most common used brand - i cant bring myself to spend $150 on a pump though. An eheim 1046 has much less head than this pump, and from the design of a rotor style block, im imagining that it would be fairly unrestrictive?
Im a total newbie to watercooling, unfortunately - I understand each part and why they need the specs they do, just putting them together and the effects are something im still learning. The products available to us in New Zealand for watercooling are pretty restrictive (only 4.2million people, in a sport orientated country - you can imagine that watercooling isnt the number one hobby here

)

Our overclockers website is drastically in need of an overhaul, but as you can see, theres not much choice. The res pump there is 400L/h with a head of (i think) 1.2m... the same pump i have just found in a garden store for 37.50. It was beside the pump i was looking at, quite funny to find things like that together
