5 out of 5 eggsAwesome build quality

Pros: - very good build quality
- allows minor customization (ie. hdd tray can be removed to allow for greater airflow)
- push button panel release (definitely a game changer)
- push button vent covers (removed during game play for great cooling)
- beyond quiet
- awesome customer service - IO panel broke on install and corsair shipped new io panel.

Cons: - the plastic hinge that holds front door looks a little weak (but comes with replacements hinges and easy to replace)
- the screw slots for power supply oddly didn't align with HX750 PSU, only got 3 screws holding PSU (which is fine)

5 out of 5 eggsClassy Case

Pros: Solid construction, Classy, professional looks, nicely finished. Dead quiet with large, quiet case fans, sound deadening material. Lots of room inside, even for tall CPU coolers like Coolermaster Hyper 212 EVO. Nice thumbscrews everywhere. Great cable management features.

Cons: limited documentation, large size

Other Thoughts: Great case to work with, no sharp edges, nicely finished, lots of room.

3 out of 5 eggs

Pros: Noise reduction works, and the case is visually appealing.

Cons: The top air duct is difficult to push open. A lot of pressure is needed to get the lid off.

3 out of 5 eggsSpeakers

Pros: On the whole, this seems to be an easy case to work with, but I'm still having trouble with the build.

Cons: This case doesn't seem to have a speaker, and I have no idea how to get one that would fit. How does one hear the ping to indicate that the motherboard is posting? My motherboard doesn't have any lights that would serve this purpose.

5 out of 5 eggsAmazing Case!

Pros: Cable management, easy. All black with white LED power button. That's basically all you see, while it might be a con that it has no window, it makes up with the fact that it's quiet. Really quiet. All of the harddrives are on rubber stoppers. The fans are on rubber stoppers also. There is sound dampening foam or some sort of material on the side panels and the front.

Cons: A 90 degree sata cable makes it alittle tight when trying to wire your harddrives.

3 out of 5 eggsCase is great, Rebate, not so much

Pros: Case is great. It is whisper quite from a few feet away. Plenty of space for drives, cables and fans. This case looks great as well. I like that the optical drives are behind a door. (Some may see that as a con but it can be removed.)

Cons: Don't bother with the rebate... They will receive your rebate from and mysteriously tthe UPC and receipt will have vanished? The case deserves 4.5-5 eggs, but the whole rebate fiasco has me slightly bitter.

5 out of 5 eggsLove this case

Pros: I love the simple look of this case, but even more than that I love the padding that helps reduce the vibration noise from my single 1.5TB drive and my liquid cooler. I'm also impressed with the removable parts on the top and side so I could add additional fans or just leave them open for airflow.

Cons: I wish the filter on the front fans was removable so I can clean it easier.

Other Thoughts: This case has been a pleasure to work with.

5 out of 5 eggsAmazing Quality & Ventilation Potential!

Pros: * Amazing ventilation potential. Although not advertised, you can add 120mm fans on the side of the HDD cages. So if you don't use the top cage, remove the brackets and put a fan at the end. Makes a great wind tunnel that shoots right against the videocard. (The screw needed are included!)
* Clean and serious look. No crazy lights or Borg looking exterior.
* Running GTX 670 core @1200mhz, i72600k@4.4ghz. Prime95 after 1 hour ~60 degrees, with 65 degree as the top spike. The video card manages to stay around 70% fan speed. ~65celcius
* ALL polished/grounded edges inside the case. I mean, I literally wasn't able to find any sharp edges. Maintenance and installation has never been so pleasant. Even the PCI vent slots aren't sharp.
* The cable management is great, although a tiny bit more space in the back would have been great.
* Plenty of space to work with.
* Side panels are really easy to install/remove. The push system seems really well designed.
* Can have a 140mm fan at the bottom of the case, pulling in cool air and shooting it directly against the GPU's air intake. That with the optional additional 120mm on the top HDD cage. That videocard is geting some serious air cooling.
* All Thumb Screws for the HDD Cages. Although they were firmly put in place by The Hulk. (I had to use a screw driver the first time)
* All ATX mounts came pre-installed... except 1? (They give you plenty)
* The HDD trays & mounts are wonderful to word with and the rubber stands slip in with ease. The side mounting with the connectors facing the rear makes cable management even easier. (Although just a bit cramped)

Cons: *Missing but a few mm in the back to squeeze in the sata cables without them pushing against the side panel. Nothing major, I just feel a tiny bump but the case closes no problem.
*Ships with a 120mm fan in the back instead of a 140mm which the socket supports.
* The foam for the PSU seemed slightly off center, a little too high. Still seemed to make a good seal.
* The dampening material is very thin on the right side panel (Motherboard side). I'm assuming this is to help with cable management, but they should have just made the case a bit wider instead.
*Wish they had put a ring of insular foam around the top and side vent panels to help further dampen the sound. There doesn't seem to be a seal other than the plastic parts interlocking, so some noise obviously bleeds out. (Take note i'm speaking solely from a silence freak perspective)

Other Thoughts: * If you do go with 2 x 140mm (back & bottom), even with Noctua fans you might want to set them at ~60% or so. Because you'll definitely hear the air rushing. At 60%, I still get astounding cooling with almost no noise. (Except when GPU goes above 60% fan speed)
At Idle, 3 foot away from the case I get ~45db, and ~40db from my computer chair.

Here are all the fans I have installed:

Heatsink: NH-U14S (140mm) (100%)
2 X Noctua NF-A14 PWM 140mm Case Fan (60%)
3 X Noctua NF-S12A FLX 120mm Case Fan (100%)
GTX 670 Fermi fan design

5 out of 5 eggsH100i fits in the Corsair 550D case

Pros: Build quality is awesome! The noise from the front intake fans is really suppressed well. I am running Corsair SP120 High Performance PWM fans as intakes in the front running at 1,200 rpms [60%] and is really quiet. I have the H100i installed at the top of the case as an exhaust config with Corsair SP120 Quiet Edition PWM fans running at 1100 rpms [80%] and is also very quiet. I left the side panel pop out off and my rig is still quiet and cool. I love this setup. Corsair has a winning combo IMHO.

Cons: This case is sleek looking in my opinion, but has one attribute that might not be desirable by some. When you touch the case, the texture of the case is course it cause it to show where you touched it. Looks like skin rubbed off. Wipes off easily but its kind of textured a bit much in my opinion. Still a really nice case, just don't touch it! =]

Other Thoughts: If you want a quiet and professional looking case, but this one!

5 out of 5 eggsA really fine, quiet case

Pros: Comfortable amount of space to play with.
Quiet, almost ridiculously so with some other noise-abating components like quiet fans and rubber washers.
Sleek look.
Easy to open for upgrades and maintenance.

Cons: All "things that would be nice": nothing here is a dealbreaker.
I'd like some more space behind the motherboard to run cabling.
I'd like the front cover panel to be able to be attached and still have the fans be useful.
