At one time, this expensive PC mod was up for sale on eBay. Yes, there is actually a PC hidden within that 1904 Chickering upright grand piano. However, everything that made this a musical instrument has been ripped out to make way for the embedded 26" wide-screen Philips LCD HDTV/computer monitor and the computer components.
The hardware specs are somewhat sketchy: 1 GB of RAM, a 500 GB hard drive, Windows XP Media Center Edition that can be controlled by a remote, and a wireless Microsoft mouse and keyboard. Naturally the piano's sliding keyboard cover can be pulled down over the mahogany "desktop" like any other key-equipped piano. A semi-hidden panel automatically slides up and covers the screen at the touch of a button.
"Wrapped in magnificent mahogany, the piano’s warm tones and unique features draw one to it," read the eBay description a few years ago. "It boasts superior craftsmanship, as evident in its intricate carved details, beautifully curved keyboard cover, and exquisite legs. It has a charming history, as many antique pianos do. But this one also has a secret."
This high-class PC was originally built for Elton John. When it hit eBay, the piano carried a huge $20,000 price tag.
