The dimensions of the case itself (LxWxH) are 546mm x 237mm x 527mm.
The Antec Eleven Hundred has nine expansion slots, so there is plenty of room for extra components, which may be a deciding factor when planning on the longevity and build type of a PC system. The case has three 5.25" drive bays, which is enough to house an optical drive and a couple of hard drives, while still having space for plenty more HDDs with the six 3.5" drive bays that are also available. You can even install an SSD or laptop-sized HDD using one of the two 2.5" drive bays. Installation of hard drives into these drive bays is made all the more easier by screwless rails that allow tool-less mounting.
