Rustyone, what x99 mobo are you using man, I know yours is really tight, I wanna check out it's dimensions to see what's comfy.
I'm looking at an MSI mobo, possibly a Godlike but this seems to go beyond the max width. A gaming 9 which is dead on the max listed width, and the gamin 7 which looks like a genuine/Standard ATX.
Board is an EVGA Classified X99, no problem with the size it was just the 24 Pin cable had to run it through the Hard Drive blanking slot.
I've just dismantled the case now,it was just a bit small for what I needed, doing a build in a Primo now.
