The Apple Mac mini "Core i5" 2.5 (Late 2012/Aluminum Unibody) features a 22-nm "Ivy Bridge" 2.5 GHz Intel "Core i5" (3210M) processor with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of 1600 MHz DDR3 SDRAM (PC3-12800) memory, a 500 GB hard drive, and Intel HD Graphics 4000 which shares system memory. 

Connectivity includes a Firewire "800" port, four USB 3.0 ports, HDMI, Thunderbolt, combined "audio line in (digital/analog)" and combined "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.

This model was upgraded to 10GB RAM and has been well looked after. It comes with the original box with UK power cable, Display port mini adapter and HDMI adapter. 

The box shows signs of wear, as does the base of the device and there is some discolouration on the cables but all work as expected. Please see evidence in photos.
