Alienware Lan party case
With the x51 being a perfect size for lan parties I think you should contact Mobile Edge and get them to make a lan party bag. This bag would have a pouch for the x51, keyboard, mouse, headphones, and a wrap around lcd cover. This would hold all of your alienware parts in a single bag for travel.
Please make something like this so I can (lan) party like its 1999 again!
