Dell has been one of the biggest (major OEM) supporter of the open source Ubuntu Linux operating system, and it seems the Linux love is trickling down to the company's boutique Alienware PC lineup as well. A new version of the Alienware X51, a small form factor gaming PC, is now available with Ubuntu 12.04 LTS pre-installed. Quite possibly the closest thing (so far) to a Steam Box, the Alienware X51 can run the Steam for Linux client along with all of the Linux games available on Valve's digital distribution service. Granted, the Ubuntu version cannot tap into the relatively-massive Windows game library out of the box, but it is also $100 cheaper than the X51 pre-installed with Windows due to Linux being free, and thus costing Dell less.
The Alienware X51 hardware is decent for a small form factor system, though it maxes out at a NVIDIA GTX 660 in the highest-end SKU. For $600, you can get an X51 will a dual-core Intel Core i3-3220 processor clocked at 3.3GHz, a NVIDIA GTX 645 1GB graphics card, 6GB of DDR3 1600MHz RAM, and a 1TB 7200RPM hard drive. On the other end fo the part configuration is the highest-end $1049 option, with a quad-core Core i7-3770 CPU clocked at 3.4GHz, a NVIDIA GTX 660 1.5GB GPU, 8GB of DDR3 1600MHz memory, and a 1TB 7200RPM hard drive.
The Alienware X51 chassis measures 12.5" x 12.5" x 3.74" and should fit into most entertainment centers (if you can get past the significant-other approval factor, that is). The PC comes equipped with Dell's 1506 802.11g/n Wi-Fi card as well, for situations where Ethernet or Powerline Ethernet is not an option.
It is nice to see Dell continuing to support Linux in some small way. Hopefully as Valve pushes for further Steam for Linux adoption, we will see more Linux-compatible games and OEMs will take notice and support the open source OS more openly in consumer lineups (a geek can dream…)!
