I own an MT-3000 case and used to have an MT-2000. I would say they're some of the finest steel cases out there. They are very sturdy, have no sharp edges, and expertly painted. The buttons feel solid and can be pressed easily.
(OK, the paint isn't automobile quality with a clear coat, but they've put a few coats on, so it's even ya know)
The front USB/mic/headphone jacks are sturdy and convenient. They use thumbscrews so you can remove the case easily. The mobo tray isn't removable, though. And you may want to cut out the fan hole punchouts (1 intake, 1 outtake) to increase airflow. But all in all, very well designed cases, and good looking too.
