My wife and I want a simple desktop for our bedroom. It is to be concealed on a hidden shelf and run to a small 21" monitor that we have on a desk. We just need it to play movies and music, and run some simple programs (Office, Aperture, etc.). Our original plan was to buy a Mini. But I'd like to do something else. I'm wondering if it will work. I have an old late-2010 white unibody Macbook that I'll no longer be using. (As soon as the new laptops are released, I'm buying an Air.) Since it still runs fine, I'm wondering if we could use it in place of a Mac Mini. Basically, I'd like to have the Macbook sitting on the concealed shelf, eternally plugged in to the power outlet (also concealed), with just a cable or two running to the monitor. Then we'd use our wireless Apple keyboard and mouse (the same ones we were planning to use with the Mini) to control everything. Will this work? I have a couple of worries. 1. Can the Macbook be fully closed, with the monitor off, while still operating normally and sending video to the monitor and being operating with a mouse and keyboard? If it can't do this 'naturally', is there some workaround? 2. Will some kind of minidisplay-to-HDMI carry both video *and* sound to the monitor? (If not, is there anything I can do to carry sound to the monitor?) Are there other potential problems? Thanks!
