OK, here's the answer.
I measured my board to see how tall a PCI Express slot is (3/8" ), how tall an IDE port is with a cable on it (3/4" ), the distance from the rear plates to the end of the PCI Ex slot (5 3/8" ). The length of the card you want can be estimated to be about 9 1/2" (compare card pics knowing the plate to end of slot is 5 3/8" ). The MB is only 8 1/2" wide, so that video card will actually stick out off the edge of the MB by these estimates of its length.
The vid card doesn't actually plug in fully to the slot so let's call its height from the MB as 5/8". That would still make it not clear the IDE port w/Gigabyte's supplied cable - if they were actually in line with each other. However, looking at the board, you can see that the PCB is not actually going to lay OVER the IDE port, just very close to it. And that card's width, it's fat part with the goodies sticking out from the PCB on it, does not extend to the end of the card. So, even though the card will come within a 1/4" or so of touching the IDE port and cable, it won't actually interfere with it. If you used a different card, with thickness to the end of it, it would interfere.
I mention testing with G's supplied cable. It has a fairly tall profile. When I look at my various IDE cables, I see only one other that "tall", most rise less height. Look at your cables and I think you'll find that with low connector height, then it's not an issue regardless.
So, you're in good shape with that MB and that card. What I don't know is if another video card might interfere with it - assuming you'd put a different card in later and still need the IDE port. I'll leave it to you to see if other vid cards are "fat" for their entire length.
Good Luck!!!
