Base on the success of HTPC 100, we enhanced it to a new HTPC 180 by replacing the panel with high-end aluminum. At the same time, we added the MCE receiver "Rack" so that user can convert the external MCE dongle receiver box internally. We also kept all the multi-functional inputs from HTPC 100, including USB 2.0 x 2 | IEEE 1394 | All in one Card Reader LCD with Alarm features and the Reset button. It comes with a S/PDIF output jack on the back. So, HTPC 180 is a truly compact and multi-function Home Theater PC case that you should consider in your buying list.
