I grew up in a neighborhood where you could leave stuff on your porch and people wouldn't touch it. Not because people in the neighborhood respected your property, but because they assumed it had no value. I remember one time I tested this theory. I placed an old but functional microwave on the front steps and labeled it as "Free". The microwave just sat there for days. But, as soon as we changed the sign to say "$20" it disappeared almost as soon as we turned our backs. I feel like computer cases are the same way. Think about it. If you build a gaming rig with $10,000 worth of parts and used one of those generic beige boxes from the 90s for the case, no one would look twice or even consider that it was anything but a piece of junk.
