I'll disaggree there, Todd.
First of all, there's a lot of computers used in offices. In fact, probably more of them than in homes.
Now a back case instead of beige, or heck, even silver is one thing. But some of the fruitier ones with windows, light and whatnot just don't belong in an office. Doubly so in any place where you have to deal with customers or clients.
Second, no offense, but I find most of them just hideous.
E.g., take windows and leds/cathodes/whatever. What can you typically see? A visiual cacophony of all PCB colours, coloured cables, copper heatsinks, aluminum heatsinks, and a led for every colour of the rainbow.
It doesn't look cool or l33t or hi-tech, it looks just sad.
For a while it at least had the novelty and rarity factor on its side. And the fact that someone worked on that. Someone had actually cut/drilled holes by hand to make that colour cacophony.
But now you can buy such things off the shelf. In fact, it's harder to find a case which _doesn't_ already come with funky coloured leds, windows and/or funny drawings. And every kiddie does have one. There is no craft or skill involved in just screwing a fan which came standard with 3 LEDs, to a case which came standard with a side window.
So the novelty has worn off, the rarity has worn off, and they certainly don't even indicate skill with tools any more.
It's time to leave that stupidity already and move on. If you're a die-hard modder, you can do better than that. And if not, might as well realize that puting cathodes in a computer doesn't make it more high-tech, just like putting a "Turbo" sign or a 5 inch exhaust pipe on a cheap 1.1l car doesn't make it a race car. It just makes it look stupid.
