The Mac mini "Core 2 Duo" 2.66 (Mid-2010) is technically a "configure-to-order" version of the Mac mini "Core 2 Duo" 2.4 (Mid-2010), but is also presented as a separate model for clarity. Apart from the processor, these two models are identical.
The Apple Mac mini "Core 2 Duo" 2.66 (Mid-2010/Aluminum Unibody) is powered by a 2.66 GHz Intel "Core 2 Duo" (P8800) processor, featuring a 3 MB on-chip L2 cache and a 1066 MHz frontside bus. It includes 2 GB of 1066 MHz DDR3 SDRAM (PC3-8500), a 320 GB 3 Gb/s Serial ATA hard drive, an 8X double-layer "SuperDrive", and a NVIDIA GeForce 320M graphics processor with 256 MB of shared system memory.
Connectivity consists of an HDMI port, a Mini DisplayPort, a Firewire "800" port, four USB 2.0 ports, combined "audio line in (digital/analog)" and "audio line out/headphone (digital/analog)" minijacks, a 10/100/1000Base-T Gigabit Ethernet port, built-in AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, and an SD (SDXC) card slot.
Unlike previous Mac mini models with polycarbonate cases, the "Mid-2010" line utilizes a "Unibody" enclosure milled from a single piece of aluminum. It has a removable black plastic base on the bottom for easy RAM upgrades, and the power supply is integrated. All Mac mini systems ship without a display, keyboard, or mouse, but many Apple and third-party options are available.
