An item code named 'Brick' is rumored to be announced on October 14th alongside a MacBook refresh. Sources tell iPhoneSavior that the 'Brick' will actually be a re-design of the Mac Mini super-sized to reveal a Mac Mini Pro of sorts. iPhoneSavior was unable to confirm these rumors.
A Mac Mini Pro could definitely be a good option for Apple considering that many users now require the use of multiple monitors. With the price point for Mac Pros so high a Mac Mini Pro could see success. The current fully loaded Mac Mini comes with a 2.0GHz Intel Core 2 Duo processor, 1GB of memory and a 120GB hard drive for $799.
Apple's 'Brick' mystery product is also rumored to be the fabled Tablet Mac by 9 to 5 Mac; however, the code word 'Brick' seems to lend itself to a larger product.
