Having A Hard Time Finding A Water Block For XFX HD 5770

[Sarg]

Hello one and all,
So here is my dilemma, I wanted to upgrade my Graphics card and I was finally able to get my hands on a HD 5770 XFX version. So I figured I would just water cool it, BUT,, there are no water blocks for this Card that I know of, I searched for god knows how many hours and all I was able to come with was this I called Koolance and they told me that i could use it and it would work. (I must say they do have good tech support I was able to get through with no effort)

Any how, It looks like this is my only option or is it?
I'm only doing one loop just the GPU, the Vregs and memory will have to get Heat sinks, that is if this is my only option. And I was thinking of getting the koolance RP-1000BK Res & pump and CTR-CD10BK Controller Seeing as I am limited on space as you can see from the pictures below, I have no problem modding a 240 Rad and I was thinking of getting yate loon fans? in to the top of the case and just take out the blow hole.

Tips / Suggestions are welcome As I am not all that sure of the Quality of the Koolance items I found

Thank you In advance
