From first inspection, I noticed that there is no internal frame on this case. Being that it is made of steel, it is very sturdy and there was no noticeable flexing (I tried to torque it a bit). Also, all internal edge have been rolled so there is little to no risk of getting cut while installing hardware into the case. The 5.25" and 3.5" drive bays have an interesting screw less securing mechanism. There are clips on only one side of the bays that swing out allowing one to insert a drive
