I have a regular PC-60 and it's super light. It's also the best damn case i've ever seen - i've heard Coolermaster is even better, but that's beyond my case price range. The Lian-Li is expensive, but I think it's worth it if you'll be working with your computer and it's not a major piece of your budget.
For my cheap server i'm using a generic case because I won't be playing with it that much and a Lian-Li would be half the price, but for any regular computer that I plan to play around with and upgrade regularly I would take Lian-Li or Coolermaster (both make good all-aluminum cases).
