Large card, both length and width, April 30, 2009
By David L.

Length: 10 9/16"
Height: 3 7/8"
Width: 1 3/8"
Measurements taken from the face of the rear plate, not the mounting lip. So if you have a midtower, and have hard drives in the lower front quadrant of your case, you may have trouble fitting this card. This is the problem I ran into, so I'm returning it. Thanks Amazon, for the awesome return policy!
