Nice deal. Looks like it will work. It's 2.5" (laptop-sized, which is a requirement), and one of the reviews on Best Buy's site for the product mention installing it into an 80GB PS3 successfully. I can't seem to find any page that mentions its height, which will need to be the standard 12.5mm or less, but since someone else already claims to have installed it into their 80GB PS3, it should work for you.
