From Orange Amplifiers: The OPC, a “fully fledged” computer that also doubles as an amp. Like any other amp, Orange’s creation accepts audio via its 1/4” TRS jack, and knobs to control volume, balance, treble, and bass (no, none of them go up to 11 unfortunately).
Visually, the OPC looks like any other guitar amp. Plug in a keyboard, mouse, and display however, and you’ll find that this amp runs Windows Home Premium 64-bit. As a computer, the OPC has a big advantage out of the box. It’s directly connected to amp-worthy speaker hardware, meaning no other computer has louder integrated speakers.
