600T, opalarrow (imo) has no taste, its a greta looking case, has great cable managemt, expandabilty, and cooling, and as alderonn said, (and i added toa lot lol), plastic doors on the front of a case? meh, they are often flimsey and you have to have them open when you are using usb or audio ports on the front, and the inside of the doors arent usually very attractive, and they get in the way, both are great caes though.
I just got back from a trip to Boston, where I had a chance to look at the 600T and the phantom in person. I have to say, the 600T impressed me. Much better looking in person than online. It's def what I'm after. Thanks.
