4 out of 5 eggsAwesome case, fan controller needs work...

Pros: Case is very good looking, and easy to build in. Cable management is easy. Very quiet if you use the right fans.

Cons: The fan controller is lame. Switching it causes the computer to lock up, I suspect because the 7V setting is replicating the "7V fan mod", which some power supplies may see as a short and protect themselves. My power supply is a Seasonic SS750KM3, which is not a cheap quality psu by any means.

Other Thoughts: You can remove the cables from the fan controller just by pulling the front panel off and disconnecting them from the header. I suggest getting an aftermarket fan controller if you must have one, I just run the two intake fans at 12V (I moved the 140mm exhaust into the front)

5 out of 5 eggsNear perfect

Pros: Good cooling options
Built in/removable 3-speed 3-fan controller
Silent out of the box; dampened panels, "moduvent", PSU standoffs+dampener.
Removable hard drive cages
Solid build quality
Supports pretty much any large CPU heatsink (170mm tall)
Blackout aesthetics

Cons: Installing SSDs behind the motherboard requires removal of the motherboard
5.25" drive bays are not removable
Top panel is not removable
Removing front dust filter is awkward

Other Thoughts: Cons haven't affected me enough to drop a whole egg, I'd drop half an egg if I could. Most of the cons come from initial building QoL. IMO 15 minutes in build time isn't a big deal.

Get a nice air CPU cooler, quiet case fans, get rid of any HDDs or optical drives and you have yourself an inaudible build.

Blacked out case feet would have been nice.

5 out of 5 eggsGreat Aesthetics, A Few Gripes

Pros: I love the aesthetics of this case. I think it looks absolutely gorgeous, but chances are if you're considering buying it, so do you.
Comes with two excellent Fractal fans, these are whisper quiet and seem to do the job pretty well. My temps aren't GREAT, but my Titan Black is superclocked. And the CPU has an H105 on it, so not really the case doing much there. It was extremely easy to mount the 240mm rad though, so if you're considering doing that, it's very intuitive. See my cons though for this one.
Everything arrived intact, so that's great. Nice box it comes in. Also, good customizability. They give you one 140mm front fan, I bought another just to add some more airflow. Snapped in pretty easily, see cons though for this one.
I really liked that I was able to take out all the hard drive cages. I have a single 500GB Samsung 840 SSD, since I pretty much just use my computer to play video games.
I love the mounting for the SSD's, you mount it on the back of the motherboard tray so it looks super clean and is great for cable management. And it fits 2 SSD's. Highly useful.
Anyway, so far I really like this case, owning it for about 3 weeks now.

Cons: Where you attach a 240mm radiator had two problems, unless I flexed the metal, like pushed it up so that it bowed, it wouldn't fit in. I don't have huge RAM, I have Corsair Vengeance RAM, so it's not like giant. Anyway, it fit in that way nicely, and maybe that's normal for cases, but I would have preferred just adding some more room so you don't have to bow the metal like that.
I read the manual, it did not tell me how to screw the fan holder in. The two 140mm fans I have in the front attach to this long plastic rectangle that hooks into the front, but they don't hook in. I just have it in between the main case and the front, it's very odd. It doesn't vibrate at all or make noise, so I suppose it was the way it's supposed to be, but it doesn't seem like they should be like that.
No motherboard standoffs installed! Jeezus, this is my first build and I would read that on cons and be like "Wow, what babies, it probably takes 2 minutes." And it does take about 2 minutes, but wow did it hurt. My thumb was killing me for about 3 days after building this, those motherboard standoffs are really, really annoying to install. A lot of cases come preinstalled, would have preferred that a lot.
Maybe it's just me, but my front LED's don't work. If I plug them in they just flicker. Also, the power on button feels really cheap and flimsy. It doesn't go straight down unless you press directly in the center, and even then a little., it's just not well made.
A lot more of this case is plastic than I expected. I also really disliked how dark the window was, they should have just left it clear. I can't see in at all.

Other Thoughts: While it does seem like I have more cons than pros, I would recommend this case to a friend. It looks good, has plenty of room for 2 GPU's, and plenty of cooling capability. This is my setup:
Intel i5-4670k
Corsair H105 AIO cooler
Nvidia Geforce GTX Titan Black
Samsung 840 EVO 500GB SSD
ASUS Maximus VII Hero Motherboard
Corsair Vengeance 16GB RAM
EVGA 850W G2 Supernova

Hope you found this helpful.

5 out of 5 eggsDefine R4 Blackout

Pros: This case is one of the best mid-tower cases that money can buy. I purchased it about two months ago for $79.99 plus free shipping. It's a big, sturdy case, that has plenty of room for cables behind the motherboard tray, making cable management very easy. Exterior and interior are painted black and comes with a tinted window. The sound dampening panels are absolutely great. They help a ton in making my computer VERY quiet. The door on the front is a nice touch that gives the case a simple yet elegant look! Four USB ports on the front panel of the case (two 3.0 and two 2.0) allow me to plug in my headphones, and multiple USB thumb drives.

Cons: LED indicator on front panel is very bright. While this isn't a big con for me, I sleep in the same room that my PC is in and when I put it to sleep it will flash constantly. Fortunately, it's a simple fix, just shut down the computer and no more flashing light! Not going to dock an egg for something that little!

Other Thoughts: High quality case, would definitely buy again.

5 out of 5 eggsDeign R4

Pros: * This case has a lot of space, at least compared to my old Hp case.

*This case is DEAD silent, even with 4+ fans installed!

*Cool temps on all of my components

*I am absolutely in love with the simplistic look and style of this case, and the window is just the right tinto IMO

Cons: I have some really small fans that i want to mount in this case but the mounts aren't small enough for them, but that isn't really the case's fault :)

Other Thoughts: I had heard many good things about Fractal, and to me, they live up to their name. You will not be disappointed!.

4 out of 5 eggsFractal Design Define R4 Blackout

Pros: Its black! Inside and out. The foam is pretty good and making stuff silent (if that is what you want). The window is smoked, so add some LEDs to the inner and have some nice effects.

The stand off tray is neatly labeled and clearly printed for A (Atx), M (Mini Atx), all a vary big plus since my last case...the stamps where sorta shallow and hard to read without putting the board in and doing it that way.

The expansion bays have thumb screws which make everything far.

As for cooling, this case will fit and has mounting holes in the top (you will have to look closely for the (circles) in the hex vents. This easily fits an H100i.

The fan filters are nice, but like most they restrict airflow, so get some fans that allow greater pressure to compensate for the full front and Bottom filters. The fan mounts in front are tool less! Yes, dual 140s just snap in..pretty cool.

Plain front, so you can turn the case to the side to enjoy a better view ( a plus for me since i like looking at my shinies!).

Cons: I only took an egg off, which i really shouldnt since the bottom fan mount (metal part) tends to bow up toward the fan and with enough pressure to cause it to stop. To fix, just dont screw it in all the way..should be fine (it is for me atm). No other cons to report.

Other Thoughts: This is a great case, pretty big for a mid tower and heavier. But you get what you pay for.

4 out of 5 eggsGreat Case. Mediocre Fans

Pros: Extremely solid build quality.
Beautiful all-black interior.
Decent cable management room.

Cons: Steel construction is heavy.
Screws are easily lost in the black interior.
Fans move minimal air even at full speed. And they only include 2 fans. -0.5 egg
Removing front filter is difficult without removing fans. Results in messed up cable management. -0.5 eggs

5 out of 5 eggsAmazing Quality

Pros: Beautiful Layout and is very easy to build in.
The Fans and Controller make life easy.
I also like all of the silent features such as the rubber bushings on every fan and power supply base to get the case vibration and sound to a minimum.
Very well ventilated and the side panels slide in and out of place very easily.
There is also no flex to them making this a very stable case.
The usb 2.0 and 3.0 ports are very sturdy and tight.
Power button has a great resistance feedback with an audible click(almost like a keyboard switch) feel as well.
The windowed side panel hides the hdd which I like and is smoked just enough.
Every single fan location 2 in the front 2 in the top one in the back and 1 on the bottom can be used in a 120mm or 140mm fan size.You can mount a H80 or similar closed loop water cooler in the top rear or case rear location.

Cons: None

4 out of 5 eggsSexy, Functional, and Semi-Quiet

Pros: -Out of the box the case is astonishingly beautiful with its all black interior especially its black tinted window and aluminum finish.
-The case is quite roomy inside of a mid-tower
-High quality rubber grommets are muchly appreciated for cable management and cleans up very well even without a semi or modular power-supply. The back has a massive amount of room to route cables as well.
-Build quality is utterly exceptional with its all metal design.
-The noise dampening foam is of a higher quality then most other foams you will see on other cases.
- Drive bays are really robust with metal construction and modular design in mind.
-Lots of air flow options with some room for watercooling support.
-The case is not massive but is above average compared to other mid towers in its width.

Cons: -The modu-vent system is pretty flawed. If you choose to leave the noise dampening covers for the two 120/140mm mounts at the top of the case, then you are sacrificing a big part of cooling which is disappointing.
-This case is not exactly silent. Sure, with my closed headset in the middle of a video, or game I cannot hear a peep out of it. But, even with my 120mm Corsair AF120 Quiet editions, it still makes quite a bit of noise.
-This case is very wide, so putting it on a desk might be a problem for some with limited space.
-Finally, the front intake is a little choked by the aluminum door. There are venting strips, but just know you will have restricted air flow from that direction, especially with the top drive cage installed.

Other Thoughts: After going from very cheap and low quality NZXT Source 210, this case is miles away from it. Super high quality construction with good looks and awesome functionality. Though it is only quiet and not silent, it is an great case for the price.
