Like the annoying little sibling we once were (sorry, sis) the Alphacool LCD squeals on its bigger sibling (in this case your PC) telling you everything it's doing. The Alphacool hooks up via USB and displays CPU load, system temperature, memory use, or anything else you want it to. You can even have it display your incoming e-mail or RSS feeds while you use your main LCD to watch a flick or play games. The Alphacool only has a 240 x 128 resolution and the display is in lovely blue-screen-of-death blue, but we still think it's a cool feature to have if you have the $240 bucks to splurge on it.
