One of the things which distinguishes the Sony PlayStation 3 from its competitors is that you are legally allowed to install another operating system onto the the gaming console which will run alongside its gaming system. This is particularly unusual, especially for Sony, who are in a constant battle to keep hackers from running homebrew applications on the Sony PlayStation Portable. Of course the only operating system you can install is Linux. This is not really restrictive, since there are so many different flavors or distributions of Linux. Also there probably would be some legal ramifications if Sony allowed you to install Windows XP on the Sony PS3. This functionality has been available since the PS3 was released.

There is a small problem though; the Sony PlayStation 3 currently comes with a maximum of 80GB of hard disk space. This is really not enough for a modern PC. The PS3’s hard drive can be upgraded, although not as easily as a PC hard drive.

Popular Mechanics has an article on “How to Turn Your PlayStation 3 Into a Linux PC“, which describes in detail how to upgrade the hard drive of a 40GB PS3 to 250GB and install Ubuntu, one of the most popular Linux distributions.
