Case placement question

Solution
It wouldn't hurt if you're able to dust it out upon occasion. Just a can of compressed air every 6 months or so and it doesn't really matter where you put it, as long as you're not blocking vents or letting a cat sleep on it. You could argue it would actually be better because its cooler near the floor.
If your case has dust filters, you should be able no problem. I have a Thermaltake A31 and it's on the ground and what I can see it that it's still clean from getting it 6-7 months ago.
