Dust Memes

The bravest programmer suddenly turns into a quivering mess when confronted with an open air computer case. Nothing strikes fear into the heart of a dev quite like those dust-collecting, static-electricity-attracting, cat-hair-magnetizing monstrosities. One accidental sneeze and your $2000 rig becomes an expensive paperweight. The only people who voluntarily use open air cases are the same people who test in production and don't use semicolons in JavaScript.
