I havent seen them widely available yet... the 7" bay is very interesting indeed. I would say it probably moves air better than a shuttle but takes up more space, and the handle leans towards less than aesthetically pleasing (but probably worx 10x better than the Q Pack handle). thats my take on it...
Just got mine today. It's a lot more sturdier than the MicroFly. The only thing that I don't like is the front 5.25 bays. You can't put any other 5.25 devices, like media display or fan controllers....unless Thermaltake can make a faceplate that can replace the existing ones. I got the Silver Aluminum one, although I wanted it in black(aluminum). I will assemble the system after Xmas, when I get the rest of the upgrades.
