Clearly Size is its only limiting factor.
cooler is near 1 1/4 inches longer then the the card its self @ 11.5 Inches making it near the 13 inch mark.
My case is masive in side so it takes it with room to grow even. But a mid sized tower like the Antec 900 and Antec 900x2 would be impossible with out modification.
Just FYI encase anyone wants to try this mod for them self's.
Few last Items as well.
Not one of the pads the kit came with was used. Every last HS used has MX-2 on it and foam pads pressed between the HSF and ram HS's where used to keep a tight firm pressure and make sure the HS's for the ram do not fall.
The shader core HS was replaced with a larger aluminum model made for chip sets. It has MX-2 on it and has plastic spring loaded push pins holding it in.
So only the HSF assembly was used for the kit and the Ram HS's and shader core HS was all custom picks.
Final product is this
and the outcome of this mod can be found above this post.
