Rofl, the fan on the outside of the case is indeed sweet, it's kindof like a fashion statement for computers, hahaha, I can't stop laughing, that's soo awesome. I wanna do it too now. :P
Ok, this's my case, the Artec Guardian, it's cool, the chasing LED light show's sweet:
Now, mine's black, and I intend to mod this beaute by swapping out the blue led's onnit and put them red, I wanna also spray me monitor black, put some red led's innit too, and same with the keyboard! more red led's! heh, it'll be.. well, black with red led's once I'm done.
... hmm... I was also thinking of cutting a hole in the top for another red led fan, dunno if I'll bother, we'll see.
