Alienware's Steam Machines won't be easily upgraded, but there will be a new model each year, Alienware General Manager Frank Azor told Trusted Reviews.

"Lifecycle wise, consoles update every five, six, seven years. We will be updating our Steam Machines every year," Azor said.

There will be no customization options in Alienware's Steam Machines, Azor continued: "You can't really update it." Customers will have small range of configurations to choose from, such as more memory or a faster CPU, he said. Those who want to beef up their machines on their own are better off with a standard PC, Azor noted – after all, anyone can turn a PC into a Steam Machine by buying a Steam Controller and downloading SteamOS.

"If you actually want to customize your Alienware Steam Machine, maybe change your graphics card out or put in a new CPU, you would be better off with the standard Alienware X51. This particular product is restricted in its upgrade options."

The first round of Alienware Steam Machines are due to hit retail in September.
