The Mac mini "Core i7" 3.0 (Late 2014/Aluminum Unibody) technically is a "configure-to-order" option for the MGEN2LL/A Mac mini "Core i5" 2.6 (Late 2014) and MGEQ2LL/A Mac mini "Core i5" 2.8 (Late 2014), but also is documented as a separate model for reader convenience. Other than the processor (and its corresponding level 3 cache), this model can be identical to its "stock" counterparts.
Connectivity includes two Thunderbolt 2 ports, four USB 3.0 ports, an HDMI port, Gigabit Ethernet, 802.11ac Wi-Fi (802.11a/b/g/n compatible), and Bluetooth 4.0 as well as an SDXC card slot.
Compared to its predecessor, this model looks identical, but it has a more advanced architecture and graphics, Thunderbolt 2 capability, and faster Wi-Fi. It also has 16gb memory configured from the factory. It retains the older 500gb hard drive.
