Can you pick up data from a computer without its cover on? I
read
a post from someone about windowed cases allowing all your data
to
be radiated out, including say.... your banking info.


NO

Unless you have a very sophisticated sniffer.

Apparently some sniffers can be synchronised to radiated
horizontal
flyback
pulses from an old CRT display, if it can also grab the RGB video
radiated
energy it can theoretically resolve what's being displayed.

There's no way to identify which emissions are R, G or B, so
they'd
only
get
a B&W image - if you're viewing bank details or top secret design
schematics, its possible it could be captured.

The logic level switching hash from an uncased PC can blot out
band
II
FM
reception, but I seriously doubt any intelligence could be
filtered
from
that mess of basically RF noise.

Perhaps the setting in the BIOS to widen the frequency band could
help
to
stop people listening in? It's meant to be for stability I think.

And which BIOS settings would those be then?

"Spread spectrum". I've never noticed a difference turning it on or
off.

Does the user manual bother to mention what spectrum it spreads?

Yes, I think it's the CPU clock. And it's to do with less interference
with other components in the system.

Find out which is the DMA chip and give it its very own little pointy
tinfoil hat.

I can see that dislodging and being as successfull as my home made water
cooling system.

The boffins in the Elektor labs tried oil cooling a hard drive by total
immersion.

Last I heard - the experiment wasn't a resounding success.
