These systems do not cause any sufficient Electro-Magnetic Force (EMF) that
can cause damage to a computer.
However the only way to make sure is to test it out. If you find that your
monitor acts funny (the old CRT types, or have a TV placed on it, and you
find unusual lines), then this magnetic field is sufficient to erase bits
of
your Hard Disk Drives or cause a sudden crash of your computer due to RAM
erasures.
The above step is given only so that you will be sure. But typically, this
contains a flexible heat coil that goes through the mat. It just heats up
to
a small degree, and so a very small current passes through it.
In any case, if you find that it interferes, just have a EMF shield bought
for the CPU. The case can also be upgraded to one that has a complete metal
cover. They are typically metal enclosures that do not have a direct
visible
contact to your CPU.
