The removal of the optical drive in the 2011 models leaves internal space for a second internal hard drive or SSD, which can be ordered as a BTO option from Apple, or as an upgrade kit from 3rd party suppliers. The 2009 model can have its SuperDrive replaced with a second SATA hard drive. Other modifications include hard disk upgrades, overclocking the processor (G4 only), and upgrading the wireless networking (for older models) to 802.11n. While opening the case does not actually void the Mac mini warranty, anything broken while the case is open is not covered. It's also possible to use wires to pull the white plastic bottom case out of the metal top case. The official Apple Service Source manual for Mac mini describes this procedure in detail, including an official Apple part number for a 'modified putty knife'. Some Mac mini owners used a putty knife or a pizza cutter to pry open the cases of older models to gain access to the interior for installation of cheaper third party memory upgrades.

Prior versions of the Mac mini were much more difficult to open. The 2010 model Mac mini was redesigned to be opened using a round cover on the bottom of the computer.
