Today, Apple updated its entirely line of desktop Macs with significant changes, including the long anticipated overhaul of the company’s popular Mac Mini, its consumer iMac offerings, and its pro-level Mac Pro desktops.

The Mac Mini has seen some of the most radical changes, given that that model had not been updated in nearly two years. Both the $599 and $799 configurations include 2.0 GHZ Intel Core 2 Duo processor, NVIDIA GeForce 9400M integrated graphics, 8X SuperDrive with dual-layer support for DVD+/-R and DL/DVD+/-RW/CD-RW, both Mini DisplayPort and mini-DVI for video output, AirPort wireless networking, Bluetooth 2.1+EDR, Gigabit Ethernet, five USB 2.0 ports, one Firewire 800 port, and optical digital/analog audio line-in and line-out ports. The $599 model ships with a 120 GB hard drive and 1 GB of RAM, while the $799 model includes a 320 GB hard drive and 2 GB of RAM. Both are expandable to 4 GB of RAM.

New iMac offerings see both a drop in price and a boost in power, with the 20-inch model now available at $1199, while 24-inch models start at $1499, the previous cost of the 20-inch model. The iMacs see a boost in processing power and RAM, and are a more minor revision than the Mac Mini release.

The new Mac Pro models have begun using Intel’s Nehalem Xeon processors and include an updated system architecture that Apple claims has twice the performance of the previous models. The Mac Pros, too, see a drop in price, starting at $2499.

Along with these changes, APple has introduced a third desktop keyboard model that is more compact than the previous version. The new wired keyboard eliminates the numeric keypad on the right end, mirroring the company’s Bluetooth Apple keyboard. It retails for $49 and comes with all iMacs by default. Interestingly, users can swap the compact keyboard for the full-size keyboard for no additional cost. Both the compact and standard versions of the wired APple Keyboard are priced at $49.
