Hi,
I have been speaking with EK and at the moment they have no plans to release the unit as a GPU cooler or the unit with out the tubing.
They may look into this again but at the moment due to the MSI card release they are not planning on doing it.
It is shame they do not release the 280 or the 240 without the CPU block, only with the QDC.
Such product will allow the rest of us who have another Predator, to expand it.
I can't think of any reason it wouldn't, as there is space for 2 140mm fans there. I don't have my 540 in front of me, but as I recall there is enough room for the rad, pump, tubes etc, as well as the 140mm fans.
Ive got a new OCUK build coming to me with this next week, what waterblock would I need for the KFA HOF 1080 edition to stick on there?
