Except that they have the fan backwards - suck air up from the floor... along with all of the dust and crap.
Unless you're supposed to have this on your desk to show it off. I suppose that wouldn't be unusual...

Both of my recent hardware failures have been caused by dust accumulating in heatsinks, so having something which contributes to that is also a "very bad idea". Especially since the air passes through a relatively confined space which you can't regularly clear out.
A common approach is to have an intake filter that catches dust. Another is to elevate the case a few inches above the ground.
