I like the mods like changing leds to cooler colors (I wanna change my green and orange ones to blue and bluish purple) and subtle stuff. I don't mind the window in there, but the sidepanel kicks ass. Yeah, goodbye ever having to unscrew the case, I can just slide a little handle thing and BANG! access. It got delivered today, and man I love it.
Most of the people who do mod have top of the line hardware inside their case even if not, why does it matter. Why do people mod their cars? Why do people renovate old houses, get cosmetic surgery? People some people have a sense of asthetics. They like things that are part of their life to be pleasing to look at. Who wants to stare at an institutional looking, bland, grey box all day? I know I wouldn't. Of course, some people don't have the money to make the choice. If I had the money I would mod-out my system like none other, not excessively though I would make sure to keep it tasteful.
