Need help with a Water Block for my GPU (Pics Inside)

Hey everyone,

Does anybody know which water blocks are compatible with the MSI GTX670 Power Edition? I know it uses a custom PCB with a 5 + 2 VRM layout but it looks like a reference 670/660ti block could fit the GPU + 5 VRM's and I would be able to add 2 heatsinks to the additional 2 VRM's; if you have personal experience or have a picture of the MSI completely disassembled, that'd be great.

MSI GTX 670 Power Edition PCB:

*Note it still has a large metal block covering the VRM's + memory modules*

NVIDIA GTX 670 Reference PCB:

Looks like the memory modules and 5 VRM's are in the same location as the MSI custom PCB.

Heatkiller GTX 670 reference cooler:


XSPC Razor GTX 670 reference cooler:


Looks like either reference 670 water block would fit and cool everything besides the 2 additional VRM's present on the MSI GTX 670 Power Edition.

Thoughts?
