How strange.
I've never liked putting cases on the floor where they can be kicked, rammed by fast-moving swivel chairs or abused by dogs. (These are all real examples of damage to PCs that the support staff at my last job had to deal with).
Omg you muppet. Theres most dust in higher places.
Why do you think, when theres a fire your told to breath in air from the ground.
Lol. Muppet.
I thought fans were blowing air out not in?
