It has occurred to me that maybe I should mention this...

Electronics and specifically, PCs do not like static electricity.  W/out explaining the science or physics of it here is my point...  Often I have gone to clients' homes or offices and discover PCs sitting on carpets.  Remember, if you rub a balloon on a carpet it will then stick to a wall?  That's static electricity @ work.  DO NOT sit PCs directly on carpets.  IF, the machine is going to be placed on a carpeted floor put something under it to isolate it from the carpet; a wooden board, newspaper, cardboard, you get the idea.

And another thing, while I'm @ it... do not remove or replace PC case covers, side panels and such whilst a PC is running.  Always do this ONLY after & while the machine is unpowered or shut off.

True...:)

Apart from static electricity issue,keeping the PC directly on carpet  will block the air flows,it'll suck in a lot more dust & may be your beloved pet's dander than it would be if it was on a desk or on a wooden board.
