What's the room around the back of the mobo tray like. Only pics I have seen show the pci-e, atx, and eps cables running up through the main chamber and not behind the tray. Also, are the 3 tops fan positions blanked out with aluminium plates. I'm guessing you will need to invest in a grille then if you plan to stick fans up there. It also looks like the HD's all mount facing outwards. More practical but kind of ugly.
Still, not that much difference overall.
