"does your side panels rattle like hexus's review claims?"
That my friend I have not experienced once with the Cosmos S. No part of it rattles. When I bought it I thought it would be loud because so much of the case is designed for massive flow through, but no it's not loud. The Cosmos S also has a slide up front panel with an e-sata connection, USB's,3.5's and firewire. Before you buy one I strongly advise you to see one in person, then see what you think. The case is also tooless for those people that love fiddleing. One thing I love about gear like the cosmos S is that is really has some design to it, I mean c'mon people love curvy sports cars and curvy women, are we suppose to settle for box shaped cases? After all it is 2008. I advise everyone on the Cosmos S, I am really happy with it other that it doesn't have castors.
The Cosmos S has handles for moving it about and for lifting it, it is a heavy case. I put a small piece of carpet under mine instead of castors so I can simply slide it forwards and backwards. Unless something else comes out that is significantly better I will be using it for my next upgrade.
