Assembling the Fractal Design Define R3
Putting together the Fractal Design Define R3 was actually surprisingly unusual. Everything goes in the usual places and there aren't exactly any particularly strange decisions, but when it came time to install our testbed into the R3, I found that parts of the inside were ever so slightly off kilter. The interior feels like one of Corsair's designs, but one that just doesn't quite come together like Corsair's do.
Installing the motherboard was easy enough, but unfortunately Fractal Design doesn't have any standoffs pre-mounted into the tray. What you'll notice, though, is that a standard ATX motherboard does ever so slightly overlap the grommets and mounting holes surrounding the motherboard tray. Our test board is by no means oversized, but the edge is maybe a millimeter or two beyond the edge of each grommet.
The optical drive bay and hard drive trays are also anything but toolless, but given the acoustically optimized ambitions of the R3, that's not too surprising. The R3 uses the same white steel drive trays for 3.5" and 2.5" drives that the Arc Midi does, and they fit in snugly and securely. You'll still have to screw the drives into the trays, but that's not altogether unusual. Meanwhile you'll also have to manually screw in the optical drive to mount it in the 5.25" bay, but at least the shield pops off easily enough; there's a small lever on the side that you push in, and the shield just pivots right out. Fractal Design includes thumbscrews explicitly for mounting 5.25" drives, and they work well.
Mounting our GeForce GTX 580 wasn't a huge hassle either, although the spacing on the enclosures we test always seems ever so slightly off, and I feel like there's at least a shred of human error involved there. When an enclosure doesn't include an easy way to mount the motherboard, there's usually a margin of error for getting it aligned perfectly and making sure the GTX 580's bracket doesn't wind up having to stretch. So the GTX 580 had to be gently nudged into place, but it was secure and mounted using a thumbscrew.
It's here that I'd like to point out that Fractal Design also includes an expansion slot mounted fan controller with the R3. You don't have to use it and for our testing I actually elected not to; there are only two fans in the case, and both can easily be manipulated using our motherboard's built-in fan control. Cabling the fan controller in the Arc Midi also served to muck up our installation a bit, so I opted to test the R3 using motherboard control instead. When we get to the results, you'll see this wasn't an issue.
Remember when I said the interior of the R3 wound up being ever so slightly off kilter? The power supply and cabling is where that comes into play. The gap between the end of the motherboard tray and the drive cage winds up oftentimes being better for routing cables than the smallish holes in the tray, but on the flipside it results in a messier installation. The interior of the R3 may in many ways look like a Corsair case, but it doesn't work out that way in practice. The hole for the cabling to connect to the power supply is too small, and the hole that was intended for the AUX 12V line above the motherboard tray is about the right size, but runs right into the top rim of the case. As a result, the plastic plug part of the cable can't fit through the gap, or at least couldn't with our testbed; it just butts up against the inside rim of the case.
If it seems like I'm making a mountain out of a molehill, you're probably right. The interior of the R3 is still by and large well enough designed, and it's not going to be particularly difficult to install a system into it. The problem is that there are all of these little things in it that keep it from being a perfectly clean and easy installation the way the Corsair cases it resembles tend to be. If they fixed the holes in the motherboard tray by lining them up better and expanding them a bit, we'd probably have a much easier time. It's a small fix, but it would go a long way.

Define R3 is an older design, that was what Fractal told answered me when I mentioned the fixed drive cage, which I as well find to be a nuisance.Coup27 - Friday, November 11, 2011 - link
For someone who hasn't kept pace with case designs for a long time, could somebody please explain why the PSU now goes at the bottom instead of the top?jrs77 - Friday, November 11, 2011 - link
The PSU sits in the bottom to make it easier to cool and less noisy. Usually PSUs have a thermal-controlled fan, which then runs faster, if it sucks hot air from within the case. That's why they get mounted on the bottom, where they can suck in fresh air instead, running cooler and more silent. Also, this setup allows for fans being mounted in the top as additional cooling for the CPU, etc.BTT:
The trick with the cable-routing is to rout the cables prior to installing the motherboard, then they'll fit through the grommets easily enough.
Well, and for cooling and noise... using better and more fans (Scythe S-Flex SFF21D) to drop both, temps and noise-levels does help.
The biggest plus for the Define R3 is the understatement and the sounddampening at a very low price.
The allways mentioned CM Silencio doesn't have the top-fan-mounts, which are pretty good for installing a 240mm rad.

For one thing, it is becoming a heavier and heavier component with increasing power needs, and I don't think 4 screws at the back and just leaving it hanging is a great idea. With it at the top you'd end up with a big shelf splitting up the case to hold it, otherwise.Bottom is actually pretty good, and it means you don't have a big mains cable trailing across the back of all your other cables round the back of your machine.

When will some half way decent Case Mfg eventually realize that when moving the PSU to the bottom, you should really move the Optical bays as well. It doesn't seem that bad in this case because its limited to 2 Optical bays, but every other case with a bottom PSU and 3 / 4 optical bays means that after installing a nice large GPU, you effectively have created a wall between the Fans pushing cool air in at the bottom and the CPU which is now way up at the top of the case.The Cooler Master Silencio 550 that someone in the comments mentioned is a PERFECT example of this.

Look at the side shot with the video card.
So that tiny slit above the right side of the video card and a whopping 1" gap between the video card and the side panel is where your CPU gets its cool air from?
Move the damn Optical bays to the bottom so they line up with the PSU (ideally only 2 bays like the R3) and now you have 2 x 120 or 2 x 140 pushing cool air in the front that line up perfectly with the components that need the best cooling. Upper fan cools the RAM and CPU and the lower fan cools the GPU(s).

Please watch this video on PBS. It is, needless to say - quite interesting, particularly if you are not familiar with fractals.

Thanks for a great article :)I however want to point out that "Methodology" is the study of methods, so unless page 4 is supposed to be teaching us the methods of testing, instead of telling us what methods were used for testing, it should be called "Testing methods", not "Testing Methodology" :)

Its no secret that the tech sites I read need better editors. Good catch. :DJarredWalton - Saturday, November 12, 2011 - link
Nope. Methodology: http://www.thefreedictionary.com/methodologyOnly 1b suggests methodology as the study of methods. 1a and 3 both support the use of the phrase "Testing Methodology", though "Testing Methods" is equally acceptable.

I don't really see anything special here.Since you mentioned the foam, can you make a an article about foam and how it effects temperatures and noise, if at all? I think the best you can do if you want a quiet PC is choose cool running, quiet hardware. A case does not make or break a silent/cool PC. Of course, that doesn't mean cases are unimportant, they can screw some things up if they are badly designed. But mostly, it's the components inside the case that should be of concern.
