Is it safe to place a computer on a carpet?

[root]

And when I had filters, they weekly completly clogged up with dust.

I never said that the solution was maintanance free...

but, (imo), cleaning a filter is a lot easier than cleaning dust from the inside of a PC...


and, (though I'm sure you probably already know this0, but dust can be conductive and can be the caase of shorts and other such things that might break a PC or cause an intermittant fault.
