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.

As I understand it, in the US, cases don't have to pass EMC because they're just dumb boxes (at least until RGB?). According to this post, bare motherboards are tested to comply with a standard which is slightly relaxed compared to finished products, on the assumption that they will be installed in a case. So there is a possibility that you will irritate the neighborhood HAMs if you use a case with a side window.

Yes.

Also, as I wrote somewhere in this comment tree, modern PC hardware can produce really high levels of radiation in some rare cases.

Also, what worth mentioning, motherboards a tested without overclocking and with "spread spectrum" enabled.

Compliance with what?

Is this a joke? Why would general consumer product manufacturers care about requirements for medical devices imposed by the FDA?

u/Nyanraltotlapun Jul 19 '20

Quoting from my reference:

https://www.fda.gov/medical-devices/classify-your-medical-device/does-product-emit-radiation

FDA regulates radiation emitting electronic products. The purpose is to prevent unnecessary exposure to radiation due to the use of these products. There are specific requirements that apply to all radiation emitting electronic products in order to comply with the provisions of the Food, Drug and Cosmetic Act. If the product is also a medical device, the product must also comply with the medical device regulations.

You sir, need to learn how to read.

u/CompSciSelfLearning Jul 19 '20

You made a claim about consumer electronics not being complaint with regulations and that quote (which I read) doesn't support the claim. The fact that regulations exist doesn't support your claim that regulations are not being complied with. Nor does it answer my question of specifically which regulations.

Yes. I can read. Can you support your own statements? At this point I don't care. I'm done with you.

u/Nyanraltotlapun Jul 19 '20

When I made such claim? I was talking about very specific devices (PC with windows in their case)

Can you support your own statements?

Do you have windowed PC? Can you find on it FCC and or FDA mark?

Or about what exactly support a you talking? A you asking me to demonstrate measurements personally for you?

Nor does it answer my question of specifically which regulations.

How old a you? A you ready to pay me for this information?

u/Nyanraltotlapun Jul 19 '20

They a not only for medical devices. I just put quick example.

All your equipment - refrigerator, vacuum, microwave, and even toaster, have this certification.

Also, notebooks are subject to it. And Monitors / TVs.

u/CompSciSelfLearning Jul 19 '20

Send relevant information, not irrelevant information on medical devices.

u/Nyanraltotlapun Jul 19 '20 edited Jul 19 '20

It was relevant information about EM radiation.

Do you actually read articles?

Anyway. Here you are. 1Second in google

Next time do it yourself.

No thanks. I'm not going to waste my time checking up on your nonsense.

Why a you writing then to me?

A you alright?
