cables tidied been meaning to do it for some time now
biggest difference id have to say is the 3x 200mm fans+all intake fans/places to put intake fans have built in easy to remove/clean dust filters
the space behind the mobo has more than enough room to hide all the cables with out the side bulging
plus and while i haven't started moding mine yet with the exception of cutting 4 small holes in the removable top grill to mount my rs360 rad the mod potential is huge
oh and the 200mm fan on the side is wired so you don't have to disconnect anything to remove the panel.
