Hey Ach - good to see you again.
This is a great case - but the problem I have with it is I have been spoiled by the very effective dust filter that comes with some Antec cases, such as on the Sonata. Our home office has bare floors and a dog! My older Antec 1040 sucks in a great deal of dust, forcing me to take the PC outside and blast it with compressed air every couple months. The Sonata, on the other hand, just needs the washable filter cleaned - no disconnecting or even opening the case. My only complaint is I have to lift up the front of the case to slide the filter out from the bottom - but that's still easier than disconnecting all cables and lugging it outside.
The other problem is all the air vents - great for cooling but not for noise control. When you start adding up all the noise producing devices: 2 or more (up to 9 in the 830!) case fans, CPU fan, chipset fan, video card(s) fan(s), PS fan(s), and drive motors - noise becomes a concern.
You did not say what the intended purpose of this PC will be - server, 3D gaming, moderating forums, etc.
BTW - I am not a fan of fancy lights - they do nothing for performance, actually add some heat, consume power, and can introduce electrical noise. Since most computers end up on the floor, out of the way, or in a cubby hole, I feel the importance of the "looks" of a computer is determined by the video card and monitor (at least after the first couple days and the novelty of the pretty lights wears off). Also, if you plan on ever watching DVD movies, the case lighting can actually be distracting - JMHO.
