One of the biggest gaming PC makers is giving its customers a free game with every new system purchased from the company. Dell's Alienware division and Valve announced today that from now on Alienware's Area-51 and Aurora desktop PCs and their M15x and M17x gaming laptops will have the full version of Valve's puzzle shooter Portal pre-loaded into their system.

The Portal freebie also comes with an install of Valve's Steam download client on Alienware's systems and is a not-at-all sneaky way for Valve's download service to be made available to all of Alienware's new customers. The PC maker will also have a dedicated page on the Steam web site with links to purchase new systems, peripherals and more.
