Hello all.
I thought it may be usefull to some people if i confirmed that the Ninja Plus Rev.B does fit on a Gigabyte MA78GM-S2H motherboard, however there may be issues with the memory modules if they have larger heat spreaders/sinks than on the Corsair XMS ones i've used.
Photos of the 'gap' are shown below. Its worth noting that the sink is pushed as far away from the memory (right in the photos) as the amd clip would allow.
(appologies if this board has already been highlighted, it wasnt in the list in the first post)
