iMac (21.5-inch, Late 2011)

Apple sold this model only to schools, for $999, beside the older education-only iMac (20-inch, Mid 2009), which stayed on sale at $899. It has the 21.5-inch, 1920×1080 aluminum case of the iMac (21.5-inch, Mid 2011). It has a 3.1 GHz dual-core Core i3, 2 GB of memory, a 250 GB hard drive and AMD Radeon HD 6750M graphics. Unlike the Mid 2011 models, it has Mini DisplayPort instead of Thunderbolt and no Bluetooth.
