Poorly constructed housing
The case is very poorly designed. Your motherboard just won't fit - you have to twist it a bit to put it in because the space for the CD drive is blocked (it's not removable).
The spacers on my CM didn't screw in, the screw thread was too narrow and sometimes crooked.
The power supply is fixed at the top and the whole thing is held together by a small metal support which does not reassure me.
My CM: (Gygabite A520M DS3H)
Seen from the outside the case is however very nice and it is one of the few that offer a CD player space.
