Boom. Just like that, the DVD drives in the Mac minis are gone. Each Mac mini now has updated Sandy Bridge technology, which in the $599 base mini now includes a 2.3GHz dual-core Sandy Bridge Core i5 processor with integrated Intel HD 3000 graphics (capable of HD viewing and light video editing), 2GB of RAM, and a 500GB hard drive. The upgraded (and thus more expensive) $799 model jacks it up to a 2.5GHz dual-core Core i5 with AMD Radeon HD 6630M discrete graphics and 4GB of RAM, and the $999 dual-500GB drive server configuration gets a quad-core 2.0GHz Core i7 Sandy Bridge processor with 4GB of RAM and integrated graphics. Is it just me, or is the Mac mini now quite a little powerhouse? All of the new models are available for purchase today.
