Any way to tighten the lid on my 17'' unibody MBP? It's too loose. Anybody call the geniuses with the same problem? Can I do it by myself? Side note to anyone thinking about getting the Speck SeeThru hard case. I generally like it. Looks good and laptop doesn't run any hotter. Rubberized surface feels awesome. But it's not light (over 1 lb). So the loose lid feels even looser with it on.
