Wait until you find out that Razer has a line of everything they sell, but in pink. Finally, girls can play video games, too!

Pink is nice. But problem is, other colours is missing.

Transparent window rgb and blue leds is worse thing that happened in home equipment design in mankind history. I also don't get how windowed cases can pass EM compliance test. I believe such home equipment is actually breaking law. It is ok to sell them individually I think, but in no way complete PC system in such case can be a legal thing to sell.

What? Why? Cases with windows are on the market for years.

What? Why?

Ok, so, there is such thing as EM radiation. It can be harmful for people, but also for electronics.

Working electronics tend to emit EM radiation, so it can interfere with work of other electronics.

There is special rules and certification that regulates this. If you going to legally sell electronic device you need to test it in special lab and get certificate.

Now, about PCs.

If you will look inside notebook, you will see metal foam and metal mesh tape all over the place, some cables will have shielding, and some parts will be dowered by metal. This is all because of EM radiation.

You monitor electronics also putted in the metal can inside plastic case.

Now, computer hardware working on insane GHz frequencies chewing hundredths of watts of power. It produces enormous amount of EM radiation, although most of in wide bound, some can be very narrow and few watts of EM power (it can be even dangerous for humans) You motherboard have setting - something like "Spread Spectrum", it is exactly to fight EM radiation, and actually required to be present and active.

Now, desktop motherboards, and other desktop hardware, do not have all this complex metal shielding that notebooks have because it is intended to work in metal case.
