The card isn't long enough to interfere with the SATA ports?
I have the gigabyte p55 ud4P , all the sata ports are front facing, angled. I stuck a couple new extra cables I have in the ports, but I can get in there regardless.
I notice a lot of people worry about measurements, more often than not , everything fits or will work with a little adjustment. Its nice to try and think of everything
but impossible. I have a slot between my cards in sli, I'd like to tell you I planned that with my choice of m/b, but I chose it at the time for other reasons, but glad I did.
