Imagine you call your friends over and tell them you want to show them your new computer....They come but they don't see any computer, All they see is a couple of consoles a TV a wooden fireplace/chimney, and a bed. they are confuse and say where is it.....You say it's the fireplace/chimney. Here are some pictures.
Mind the dust will you :wink:
Anyways of course the screen would have to be a bit more above it's original position. The Back can hold More than enough Hardware and wires. No one would even think you own a PC when coming into your room. So when starting it up just say "lets fire it up!"
Here is a smaller version of what it would be.
Courtesy of my own 2 chimneys by the way.
EDIT:Of course this in a size of a regular computer would be out of this world!
2nd Edit:This would be somewhat where the USB's CD-DVD would be and other things too.
