Aluminum cases don't really give lower temps, that's a myth. Well, in my case it did, but only because my PC7 is a bit roomier than my old case was, nothing to do with the material. I bought it because it was a little bigger and looks nice, but mostly because it's really light.

It's hard to say how much the aluminum makes a difference, since every case is different. However, I can say that the benefits of the Lian-Li go beyond the material. It's a very well-designed case that is very easy to work with. I'd recommend it to just about anyone.
