Power button and LED issues behind me. This is a huge chassis that looks amazing, is designed with silence in mind and has ventilation to redirect noises, and sound absorbing materials applied, and is a chassis that cools really well on air, but also offers water cooling enthusiasts a case with placements for up to four radiators, and still have room for a loaded system and all the rest of the water cooling gear. NZXT really left no stone unturned with the H630 chassis.
The matte finish on this chassis is like no other case I have seen, and makes the plastic front bezel blend into the steel components of the exterior with a perfect match. The design is simple, yet elegant, and offers just a touch of angles and panel lines to give it a bit of character. On the inside it is a whole different ball game. The sheer amount of fan options inside the chassis, amount of places to store up to ten storage drives, an over abundance of wiring options, the list just goes on and on. Even if the aesthetics are something too plain for you, I can see that this chassis is going to be a perfect candidate for chassis modification. It has everything a modder wants on the inside, and the outside is a virtual blank canvas waiting for you to make the H630 your own.
Depending on where you are located in respect to the chassis, the noise levels will vary. In the front of the chassis things are dead silent. At the left of the chassis you can hear 33dB of noise level, as the sound works its way from inside of the case and out the venting at the top. The back of the chassis is where I got the highest reading of 39dB. Seriously though, who has the back of the case facing them? The right side also is where the chassis gets its intake of airflow, and while somewhat silent, I got a reading of 34dB here. Since the normal range of hearing stops at 25 to 30dB, the chassis does keep in line with the "silent" design that NZXT were looking for from the start. One thing I will add is that with just a single 200mm fan in the front and the 140mm stuck in the back, temperatures inside of this chassis are very cool as it is shipped. I can only imagine how good it will be with more fans, even water cooling with some high pressure, but low noise fans.
Now I really hope you can see why I was so blunt at the start where I said you were getting quite a bit of case for the money. Every way you look at it, any way you try to listen to it, the H630 is the largest, most silent, feature rich solution I can think of for this price point. When the H630 Ultra tower does finally make it to the shelves with a price tag of $149.99, I see an issue with anyone being able to keep stock long. This chassis is just that good. NZXT shows once again why they are getting so much respect in the chassis game - because they aren't afraid to load up a very nice looking chassis, and offer it with an appealing price point.
If you want a silent chassis that can grow with your ideas of water cooling and much more, I definitely suggest that you take a long hard look at the H630 Ultra-Tower chassis from NZXT.
