It's the same as a car enthusiast would want the engine compartment of his car all perfect, shiny and bling. A lot of cable management techniques come from automotive and industrial, where sleeved cables were around from long before computers went mainstream.

So while most people don't care about what is under the hood of their car, there are those that do.
The window came about just so we could admire our work without having to take off (and run without) the side panel.
There are certainly a lot of users that follow this, judging my the sheer number of posts in threads like this over the internet, but truthfully we are still a minority. It is hard to fathom just how many basic systems there are out there, millions (probably) of just the new Dell Studio Hybrid (

The vast majority of users these days don't know how to take the side panel off, or plug in the cables correctly, or know what is actually in their system. But I think some of them wander into threads like this and the next system they buy is often home built, custom and bling.
It has become an artform, for sure. Like furniture and decor, it is a statement of the owners personal taste!

Why everyone cares so much about wires inside the case?
I though the whole purpose of the case is to hold components and hide interconnects.
So, you see nice looking box with some whoozing electrocrap inside.
Also, I do not get case windows. I think I am old.
