Hello Computer People,

Can anyone tell me what mini tower
is best for shielding of electronics
components contained within ??

I have seen so many towers that have big holes cut
in their sides for Plexiglas covers and lights and stuff
but those kinds of towers must leak RFI like a sieve.
They should provide no protection against things like
RFI and EMP.

Any comments in regard to this hazard is appreciated.

It's not a mini tower, but you'll get decent shielding:

Get a decent case with no extra holes. If you want extra sheilding, there
is a conductive sheilding paint available as well, but it is expensive.
Adequate filters in the Power supply seem to have more impact on RFI than
most cases do. If you are worried about EMP, what branch of the
government do you work in ;-)

If you like the tacky look, aluminum foil
sandwiched between the plexiglass and
case (so as to make electrical contact with
the metal case) will do. If you like the
mysterious look - neon glowing innards
dimly visible through a dark haze - sandwich
a layer of aluminum screen and silvered mylar
in place of the foil. If you like the secure
industrial look, substitute a steel plate in
place of the foil. Even better, yet - get a
beige tower and stencil "Property of U.S.
Government" on the side.

I work for the Executive Branch.
Have so for the past 49 years.

We should all be thinking about this EMP stuff
because the government is putting serious work
into it and it does not take the form of
nuclear bombs anymore. It can be used simply
to corrupt and not to destroy.
Computers are becomming some what critical to
everyday life so serious thought should go into
EMP & RFI shielding.

Fiber optics should be used for I/O as well
as faraday shielding. I see no serious effort on
the part of the US to combat the infernal idea
of EMP or RFI when it comes to the general public.

I noticed you seem to be answering a previous post
but this post is the first reply I see in this thread.

Here is the consumer reality as far as EMP goes. Any Electro Magnetic
Pulse sufficient to disable a current home/business computer system is
going to take out most of the electronics and communications equipment in
the. EMP damage can be caused by very few things. Lightning can do it.
Exploding substation/power pole transformers/major power system failures
can do it. Nuclear devices are what started people looking at EMP, and a
new generation of EMP weapons that are being tested and maybe deployed by
governments around the world.

Lightning can't be completely protected against. Proper grounding,
lightning rods, full house surge protection, proper utility installation,
etc. make it less likely but a close strike will do damage.

Freak power grid problems are pretty much like lightning. Have fixed one
system that was damaged by the pulse of a large power transformer in the
area shorting out and exploding. Computer was not even plugged in at the
time.

If damage from Nukes or EMP weapons is a threat to you as a normal
business/consumer, you have much larger problems than EMP to worry about.

I just think it to be the duty of this high tech world to
keep things where they belong.
Outside RFI and EMP should be kept out of all
delicate electronic equipments like computers
and radios and TVs usw...
and all self generated RFI should be contained within
whatever device is generating it.
From the reading I have been doing I have found EMP
weapons can be designed to corrupt a system and not destroy it
causing a computer to lock up and stuff like that
things that look like an internal problem can easily be caused
by external things like EMP or RFI.
If EMP devices are to get in the hands of law enforcement
they will be in use all over the country and unless
your machine is protected against such a thing you
might easily become an innocent victim when such a device is used.
Also RFI is a transmitter of confidential information
so containing it should also be of interest to
everyone playing with High Tech toys.
If it does not become common practice to guard against
these things it troubles me very much.
I will not loose sleep over it but still it troubles me to think
people are so careless about such things as protecting themselves.
Terror can take an infinite variety of forms and not just killing,
limited only by the human imagination.
 
If you have water cooling inside your computer
you might worry about corroding.
Corrosion forms non-linear devices and
non-linear devices can cause RFI.
