The original PlayStation 3 was one huge machine, and modding it into a laptop was probably unsuitable. But when the smaller PS3 Slim came about, modder extraordinaire Ben Heckendorn decided this was the right time to change his gaming console into a portable.
Granted you'll probably need a large backpack to transport the unit, and it does not sport a battery pack. Nonetheless, it's impressive how he managed to integrate an HD-ready 17-inch display into the gaming console. Heck claims he could have made it smaller but wanted to keep the screen size usable. Check out a video of his laptop/gaming console mod below.
