iMac 20" 2.0 GHz (EMC No. 2266 Edu) Prying and Opening
Released in April 2009, this iMac was originally only available to educational institutions. It is similar in construction to early 2009 iMac models, but has a slower processor, a smaller hard drive, less RAM, and no support for internal Bluetooth. It can be identified by its model number A1224 and EMC number, 2266, both of which are located beneath the single foot.
