I hate loud, dusty computers. They make me want to puke.
 
The Corsair 600T is an excellent chassis. It's big, with lots of interior room and oodles of enthusiast features which makes it ideal for positive air pressure environments. Unfortunately, the interior also reflects system noise due to its two huge steel side panels, and because I use positive air pressure in my builds, keeping dust at bay is always a challenge. After some thinking, I decided to sound proof this case and while I was at it, toss in some custom cut fan filters to keep the dust bunnies at bay. Here are the results!
 
Right side panel complete with sound proofing material installed, overlaid with fan filter material. The white plastic piece is the bottom mounted frame for the filter of the power supply (yes, I filtered that too as well!).
 

 
 
Both side panels have been sound proofed. The sound proofing material is AcoustiPack Professional Sound Dampening Material (APExtS). Each sheet is 18" x 17" and is 7mm thick thanks to its 3-layer design and very heavy. The sheets also smell weird, too.
 
The AcoustiPack sheets can easily be cut to size. The easiest method I found to install the material was to lay one large sheet of sound proofing material inside the panel and then trace the cutouts that needed to be cut away. Using a piece of chalk to outline the parts that needed to be removed is ideal. A damp rag easily wipes away the chalk lines once you're done sizing the material. A very sharp pair of kitchen shears are suggested for optimal results.
 
Each side panel of the 600T needed about 1.75 sheets of AcoustiPack material to finish. I went ahead and filled in every crevice of the side panel, even going so far as to sound proof the mounting bracket on the bottom of the panel that fits into the three-slot support ledge inside the chassis.
 
 
 
 
The easiest way to install sound proofing material is to have patience. The sheets have double sided sticky tape already added to them, so you just simply peel off the backing and place the sheet down where you want it. The tape is insanely sticky though; make sure you're absolutely sure of the placement of the sheet because once you set it, you can't remove it without ripping the material. The best method is to lay the material down and peel the backing away a little bit at a time while sticking that portion of the material down.
 
Once placed where I wanted it, I used a small 3/8" dowel about 6 inches long to roll the material like dough, making sure that the tape adhered the sound proofing to the side panel.
 
The thickness of the AcoustiPack material is exactly the same thickness as the depth of the side panels, which is nice because the panels are able to close and stay flush with the frame of the case without the panels sticking out, as shown below. The 600T originally comes with one solid side panel and one windowed side panel. However, I'm not one for windows in my cases, so I obtained another solid side panel and used that instead of the windowed one.
 

 
 
The interior of the 600T with the back side panel with sound proofing material installed, as seen through the square-cut hole at the bottom of the case near the HDD cage. Even with the material installed, there is plenty of room between the side panel and the back of the motherboard tray for wire management duties.
 

 
 
Shameless plug of the backside of the PC with the side panel removed. My wire management skills have not yet reached epic levels yet.
 

 
 
The front of the 600T incorporates a 200mm intake fan. The filter that comes stock with the case is woefully inadequate to prevent dust-buildup, especially in positive air pressure builds, so I initially augmented this area with fiberglass-based commerical HVAC filter material that could be cut to size.
 
Unfortunately, I realized too late that fiberglass-filter material is terrible once you cut it, as thousands of tiny fiberglass particles fly everywhere and imbed themselves into the filter material which you can never fully remove. This problem was only exacerbated when the intake fans would blow these particles all throughout the inside of the 600T, leaving me a mess to clean up.
 
Okay, lesson learned and back to the drawing board. I headed to Sears to pick up some synthetic fiber material instead and found some Kenmore HVAC filter material (Model number 14916). This stuff is originally meant for dehumidifiers that use a rotary design, so I had to cut the filter in half to make one long piece out of it. I used a black Sharpie to make an outline and used scissors to cut it out.
 

 
 
Quick shot of the front panel installed over the filter material. The neat part about this is that the 200mm fans that Corsair includes with the 600T incorporate white LEDs. The filter material diffuses the white LEDs so that they quietly glow.
 

 
 
The top of the 600T also was treated with some filter material love as well. The black mesh panels snapped easily into place after cutting out and installing the filters in the case. Each filtered area has been doubled up, meaning that I am using two cutom-cut filters laid on top of the other for maximum dust prevention.
 

 
 
Okay, so how well did the sound proofing material do? I don't have a dB reader, so this is purely guesswork on my part. However, before the sound proofing material was installed, the case was loud. I could easily hear it running across my office when idle, and especially if it was going full tilt while gaming or Folding (you ARE folding for Team EVGA aren't you?).
 
Now, with the material installed, you cannot hear it at idle at all. You have to put your ear close to the case to even tell it's running now. If the white LEDs didn't give it away, you'd swear that the PC was shut off. With the PC running at full tilt however, the sound difference is tremendous. Before it was almost unbearable, now it hums quietly.
 
As far as heat issues are concerned, I haven't detected any significant increases. I'd give the variable +/- 2 degrees but that's about it. Because the 600T has such a large interior, and the fact that I am running a pure positive air pressure environment in my chassis, heat issues have not posed a problem at all.
 
One thing that has increased is the weight of the case. The sound proofing material is friggin' heavy! I would guess that by installing nearly  four sheets of the stuff in my PC, it added about 7-8 pounds of extra weight.
 
So what do you think? Is this something you would do to your own PC? Feel free to comment and give my PC some +1 Mod Rigs love!

Great work there!!

Nice and clean, that's the way I like it! Good job, bro!

Very nice. I have three GPUs that need a lot of air, otherwise I might have used your idea.

Very nice and clean build. I like it. Nice job on sound proofing. one thing I hate is the noise from PC components.

Nah I dont think there is no draw back whatsoever with me cutting out my mesh. I don't care about the dust issue. Your system with those filters is still going to get dust in it regardless. All your doing is just slowing down the dust build up by sacrificing cooling performance. All you need is canned air bro. Its easy to clean the system with canned air. Also I disagree with you about the white led fans that come with our case. Come on bro we all know that all stock case fans suck so those 200mm fans suck. Especially that stock exhuast fan. It only blows out 32cfm. I replaced it with a blue sickoflow fan that blows 69cfm. The white 200mm led fans only blow 90cfm. I replace the front one with a Bitphonex as you can see in my pic which blows 148.8cfm. On the top of my case I replaced it with 2 120mm fans that are the exact same as my exhaust for more air and pressure. Well its your rig and its up too you my man. Just trying to give you advice. I hope you enjoy your PC as much as I enjoy mine. I personally think me and you have one of the best cases in PC hardware.
