The Apple Mac mini "Core 2 Duo" 2.53 Server (Late 2009) is equipped with a 2.53 GHz Intel "Core 2 Duo" (P8700) processor, featuring a 3 MB on-chip L2 cache and a 1066 MHz frontside bus. It comes with 4 GB of 1066 MHz DDR3 SDRAM (PC3-8500), dual 500 GB Serial ATA hard drives, and a NVIDIA GeForce 9400M graphics processor that shares 256 MB of memory with the system.
Its connectivity suite includes Mini-DVI and Mini DisplayPort, a Firewire "800" port, five USB 2.0 ports, combined "optical digital audio input/audio line in" and "optical digital audio output/headphone" minijacks, a 10/100/1000Base-T Gigabit Ethernet port, plus integrated AirPort Extreme (802.11a/b/g/n) and Bluetooth 2.1+EDR.
Late 2009 Mac mini models have their components housed in a compact and elegant 2.9 lb, 6.5-inch square, two-inch-tall case with a built-in speaker and an external power supply. All Mac mini systems are sold without a display, keyboard, or mouse, but many Apple and third-party options are available.
Please be aware that this model is identical to the Mac mini "Core 2 Duo" 2.53 (Late 2009) model, with the exception that the "Server" version is fitted with dual 500 GB hard drives and lacks an optical drive, utilizing a modified case design without an optical drive slot. It was also shipped with an unlimited user version of Mac OS X 10.6 Snow Leopard Server instead of the standard Mac OS X 10.6 Snow Leopard.
