How to avoid a dusty computer

Put simply, computers of all types do not like being on the floor, especially if you have carpet. The computer need to be in the most dust free area of it's surroundings.

Here is your typical scenarios:

The computer tower's fans will pick up all the dust, carpet, pet hair and whatever is floating around being kicked up by everybody's shoes, and blow it inside the tower case. Over time this dust builds up to a point where fans stop turning altogether.

This can be very serious indeed.

This photo is of an extreme case of dust bunnys, granted, but I have seen machines this bad in my career.

The risk of a dusty computer is relative to it's environment. I believe that the higher the tower is off the ground the better. I have my machines 1 inch from the roof on shelves. I haven't cleaned them in 3 years and they still look good.
My storage scenario is an extreme one, but it also saves on space.
The minimum your computer should be off the floor is 40cm in my humble opinion.
