Xbox 360 Elite laptop. If this seems vaguely familiar it's probably because you're remembering Heck's Xbox 360 laptop how-to design guides from last spring. The difference here is that this one is a modded Elite with built-in camera and other upgrades (video after the break).
If you're just hearing Heckendorn's name for the first time here, please feel free to take a trip down memory lane. Other mods of interest created last year include the Wii laptop and the freaky PS360 gamepad.
