Thermaltake's M9 caseis a straight forward case with all the nods towards keeping itself modern and useful. It stands 17" tall and 7.5" wide and is constructed out of plain old SECC steel, glossy black plastic, and mesh grating along its front bays. There's room inside for six 5.25" optical drives and three 3.5" bays in its default configuration, although that can be changed to open up as many as nine 5.25" bays by removing the hard drive cage.
