The Apple Mac mini "Core i5" 2.5 (Late 2012/Aluminum Unibody) is powered by a 22-nm "Ivy Bridge" 2.5 GHz Intel "Core i5" (3210M) processor, containing two independent "cores" on a single chip and a 3 MB shared L3 cache. It includes 4 GB of 1600 MHz DDR3 SDRAM (PC3-12800), a 500 GB hard drive, and Intel HD Graphics 4000, which shares system memory. An internal optical drive is not included, though an external one could be purchased for US$79.
Connectivity features a Firewire "800" port, four USB 3.0 ports, HDMI, Thunderbolt, combined "audio line in (digital/analog)" and "audio line out/headphone (digital/analog)" minijacks, a 10/100/1000Base-T Gigabit Ethernet port, 802.11a/b/g/n Wi-Fi, Bluetooth 4.0, and an SDXC card slot.
In comparison to its predecessor, this model appears identical externally but boasts a faster internal architecture with a more powerful processor, improved graphics, faster RAM, and the addition of USB 3.0 ports.
All Mac mini systems are sold by default without a display, keyboard, or mouse, but a wide range of Apple and third-party accessories are available.
