From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

When I talked about EM shielding I wasn't strictly talking about shielding metal plates inside your computer. Although certain components might be shielded with metallic plates most components are tested for EM compatibility with other devices (they have to by law) and there are different possible levels of EM interference resistance and hardening. What I've noticed with cheap brands is that their components usually tend to be cheaply built and very susceptible to EM interferences. This doesn't happen in brands like HP or Asus, they take a lot of attention to that detail. And yes, that typical copper heat shielding sometimes doubles as EM shielding.
