The entry level model will also come with 4GB of RAM, and a 500GB hard drive.
USB 3.0 is now standard on the mini, which will start at $599.
The server version will cost $999, and includes a 2.3GHz quad-core i7 processor and two 1TB hard drives.
It is possible to use Apple’s new ‘fusion drive,’ where a hard drive is combined with flash storage.
