The Mac mini Late 2014 included a Core i5 “Haswell” 2.6 GHz Intel processor (with two independent cores on a single chip), 8 GB of SDRAM, and a 1 TB hard drive. Ports included two Thunderbolt 2 ports, four USB 3.0 ports, an HDMI port, Gigabit Ethernet, 802.11ac Wi-Fi/Bluetooth 4.0, and an SDXC card slot.
This and all Mac mini systems ship without a display, keyboard, or mouse. This model’s case is primarily aluminum with a black plastic back and base.
All Mac mini systems I have owned have served as my iTunes server allowing access to iTunes music/Apple Music, streaming video content, saved digital movies, and other media. This was the first Mac mini I owned with a direct HDMI connection to my primary home TV (others used VGA and DVI connections).
