9to5 Mac reports:
“These new Mac minis are said to begin shipping immediately after announcement. Apple last redesigned the Mac mini with a unibody aluminum enclosure in 2010, and last updated the computer with faster processors last summer. These current Mac minis are on last-generation chipsets and lack USB 3.0, so we should be seeing those components updated in these new models.”
The updated Minis will be available in two standard versions and a third model that runs Mountain Lion Server.
The iPad mini, a 13-inch Retina Display MacBook Pro, updated iMacs and updated Mac minis are all rumored to be presented at the October 23rd Apple media event.
