The Xbox 360 (sometimes referred to as Pro or Premium and packaged as simply Xbox 360 with the subheading "Go Pro") included all the features of the Xbox 360 Core and included a hybrid composite/component cable with optional optical out instead of the composite AV cable included with the Core. This model also included a detachable hard disk drive (initially 20 GB, while later models had 60 GB) to store downloaded content, provide compatibility with original Xbox games, and store game data. The included hard drive came with game demos, video clips and a free Live Arcade game, Hexic HD. In July 2007, this version of the Xbox 360 began appearing with the Zephyr motherboard (the motherboard used in the Elite) which features HDMI 1. 2 output and an improved GPU heatsink. Although this model did include an HDMI output, it did not come with an HDMI cable. Starting at the end of September 2007, the newest systems were shipped with the new "Falcon" motherboard. This motherboard includes the new 65 nm CPUs, making them quieter and cooler than the older systems. On August 1, 2008, the 20 GB version was discontinued and was replaced by a 60 GB HDD model at the same price. Holiday 2008 consoles were bundled with Lego Indiana Jones: The Original Adventures and Kung Fu Panda. Price cuts that took effect on September 4, 2008 reduced the price from $349 to $299. The Xbox 360 configuration, following its discontinuation, retailed for $250 until stocks were exhausted.
