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.
