You're assuming it's a low-profile card because of a photo? I see the card doesn't span the entire faceplate, but to assume it's the right height to be considered low-profile based on a photo is a presumptuous, no? Why wouldn't MSI state low-profile/half-height in the specs?
What makes you say this MSI card is low-profile? I can't find anything that says that. You can now buy it in N. America (ewiz.com, for example), so I'd like to get that card over the Galaxy because it has HDMI outputs, but I need to make sure it really is low-profile. Can you share your info...
