As a computer, the OPC runs an x64-bit version of Windows 7 Home Premium on an Intel Pentium Processor E5400 (2M cache, 2.70GHz, 800MHz FSB). The graphics card is an Nvidia GeForce 9300 overclocked to 580MHz. A 7,200rpm, 500GB hard drive comes standard, along with 4GB or RAM, HDMI/VGA/DVI video output, seven USB 2.0 ports, and one eSATA port. There's also a top-loading DVD±RW and an 802.11g Wi-Fi antenna that sticks out from the top.
Beyond the aesthetics of the orange tolex covering and wheat-colored grille cloth, Orange also went to the trouble of integrating quarter-inch guitar and mic inputs in the top, along with knobs for volume, treble, bass, and balance.
