What ports are provided by the Aluminum "Unibody" Mac mini models?

The now discontinued "Mid-2010" Aluminum "Unibody" Mac mini models -- the stock configurations of which are the Mac mini "Core 2 Duo" 2.4 (Mid-2010) and 2.66 Server (Mid-2010) -- have identical ports and connectivity.

The current "Mid-2011" Mac mini models -- the stock configurations of which are the Mac mini "Core i5" 2.3 (Mid-2011), "Core i5" 2.5 (Mid-2011) and "Core i7" 2.0 (Mid-2011 Server) -- also share the same connectivity with one another, although there are a few notable differences between these models and the earlier line.

The "Mid-2010" Mac mini models includes both an HDMI and a Mini DisplayPort -- capable of passing an audio signal as well as video -- for simultaneous support of dual displays, a Firewire "800" port, four USB 2.0 ports, combined "audio line in (digital/analog)" and combined "audio line out/headphone (digital/analog)" minijacks, a 10/100/1000Base-T Gigabit Ethernet port, built-in AirPort Extreme (802.11a/b/g/n), and Bluetooth 2.1+EDR, in addition to an SDXC-capable SD card slot.

The current "Mid-2011" Mac mini models have the same ports with two exceptions. The "Mid-2011" models swap the Mini DisplayPort from the "Mid-2010" models with a new "Thunderbolt" port. The "Mid-2011" models additionally support Bluetooth 4.0 rather than the older Bluetooth 2.1+EDR standard.

What type of keyboards and mice does the Aluminum "Unibody" Mac mini support?

All Intel Mac mini models -- aluminum and otherwise -- support essentially all USB-based keyboards and mice, ADB-based or PS/2-based keyboards and mice with adapters, and Bluetooth wireless keyboards and mice. If you use a third-party keyboard designed for Windows, a Mac mini will treat the "Windows" key as a "Command" key and the "Alt" key as an "Option" key.

For additional information on keyboard compatibility, please refer to "Mac mini: What Keyboard and Mouse to Use" and for additional information on third-party keyboards, please refer to "Third Party Keyboards May Not Have Command, Option Keys" each from the Apple Support Site.
