Conclusion: Iterative, But Still Needs Work

With the Define R4, Fractal Design has again produced a solid case that has a lot to offer end users. I'm very fond of case designs like this one and the AZZA Genesis 9000 that give the user a great deal of flexibility in how they want to assemble their system, and I like that Fractal Design lets you optimize for acoustics or for thermal performance. The included three-channel, three-setting fan controller is also greatly appreciated and a marked improvement over the R3.

As a general rule it's good to continually reward improvement and innovation from vendors, and the Define R4 is absolutely a better case than the R3. The problem is that enclosures are one of the places where a lot of innovation is occurring on a regular basis as companies continually revise existing designs and introduce radical new ones in a bid to further optimize system cooling. System cooling is a science that is still miles away from being perfected and probably never will be if for no other reason than that there are simply too many variables to take into account. Engineers have to find the right balance for their product and plant the flag there.

I don't think Fractal Design's engineers were daring enough with the Define R4. This is by no means a bad case, but there are places where technology has improved that Fractal Design could definitely have adopted. For example, SilverStone's Temjin TJ04-E aligns the top fan mounts to the left side of the case in order to improve clearance for increasingly popular 240mm radiators. This is an easy enough change to institute that notably improves the usability of the case. Likewise, switching to hinged side panels allows for clearance for routing the AUX 12V line. Fractal Design could also save some width by introducing cabling channels in the motherboard tray similar to what Corsair did with the Vengeance C70. These aren't changes that are going to dramatically improve the R4, but they're easy ones to implement that make the case more usable without driving up the cost.

Speaking of cost, that's one place where I do think Fractal Design nailed the Define R4. While I wasn't supremely impressed by its thermal performance, I do think it's worth the $10 premium over the NZXT H2, and does a better job acoustically than the $10 pricier Antec P280. $109 is a great price for a case this feature rich and well built, and while the Corsair 550D is a generally better performer, it also has more trouble spots that give me some pause in regards to its longevity. Couple that with an extra $30 on the price tag, and the Define R4 looks a lot better.

Ultimately, I think if I were building a quiet system on a budget for someone, I'd have an awfully hard time finding a better choice than the Define R4. The case absolutely has room for improvement and I wonder if potentially more efficient case fans like SilverStone's AP121 or Corsair's new line wouldn't give us better thermal results, but the $109 price tag is very hard to argue with when you take into account what you get. The R4 isn't a slam dunk, but it's definitely worth your consideration.

    Fractal Design rates it for 15mm, but I'm still of the opinion that your mileage may vary due to VRM sink design, etc. If it's going to fit it's going to be awfully tight, I don't think I'd try it in this case.

    Thank you for the response. Sounds like a water cooling in this case is a lost cause. Oh well.

    actually there is not a single review that says this but the button hard drive cage can be moved back and a 240mm read can be installed in the front. there is a YouTube video from fractal that shows this

    I just picked up the Arc Midi, which I love aside from one small issue. In the removable cage, you cannot put a 3.5" drive into the top bay. The screws that secure the plastic bits on top protrude down too far and it scratches the top of the drive. I suppose if I felt like gouging the crap out of my drive I could put one there, but fortunately I /only/ have 6 hard drives and 1 SSD.

    "Evolution not revolution" and variations thereof must be the single most overused literary cliche in tech journalism, every time I read it I shudder.

    It's the influence gaming has had on the current generation of writers. Although, I'd personally take "evolution not revolution" over "rare(fied) air" (which seemed to inexplicably sweep the nation after Drew Brees passed Dan Marino's passing record last season, even creeping into Anandtech) any day.

    Seriously speaking (as a hack novelist who makes less money from writing than most HS kids do from their summer jobs), I find that even though the writers here at Anandtech all have their own idiosyncrasies which they can't help but put on display considering their output, they each have their own distinct "voice" and do a good job not just parroting their fellows' expressions, anecdotes, opinions, metaphors, and what have you. As opposed to AM radio personalities, ESPN's in particular. If I hear Jeremy Lin described as a "gift from the heavens that fell into the Knicks' lap last season" one more time (after hearing it used on just about every ESPN radio program just about every day this week) I'm going to throw whatever the offending phrase issued from into the nearest bay. Even if it's my manager.

    Sometimes I can't help it, and I've found myself often even accidentally or almost repeating myself in headlines. It's tough to consistently come up with new stuff when you write as much as we do. ;)

    At the risk of tooting our own horn a little bit, Anand pretty aggressively courts (and has us aggressively court) people who have some writing skill in addition to their understanding of technology. From there, our editorial process has been in my experience devoid of any stylistic editing. I've written for a few sites, but these are seriously the nicest and most genuinely talented guys I've ever worked with.

    I love the monolithic front look of the case with no bays or grills. I also appreciate this case bucking the almost universal trend of putting three or four and sometimes even five useless 5.25" bays. Doing so builds the option of having much better cooling or many more hard drives.

    Other than the power button, the ports on the top of the case seem a bit silly. I can't imagine why I would use the audio ports for my speakers. I can't imagine use them for headphones instead of the headphone port on my speakers or remote dongle. Same for the USB, just use the one on my computer/monitor/keyboard/speakers all which seem like they would be more convenient. I wouldn't care so much but it seems like those top ports will get dirty quickly and become unsightly.

    I also agree with other posters that the top ports shouldn't be there. My current case has a vent and fan on the top and I will never get another case with them again. You can stack anything on top and my son loves to put things into them.

    Finally, If they really want to do a revolution for the next iteration of this case here is what I would do. Ditch the 5.25" bays entirely. Reduce the width of the case as much as feasible while still keeping the 3.5" bays mounted the same. Ditch the lateral expansion slot if it helps reduce case width. Ditch ATX support along with 3 of the 7 expansion slots to allow the case to be shorter.

    Actually, I love the top vents on my Coolermaster CM-690, and wouldn't buy a case without them for a performance build.

    This looks like a very good case even compared to the CM-690 series, except I don't want a door. Is it removable? I hope so.
  • Grok42 - Sunday, July 22, 2012 - link

    I would prefer not having a door as well to reduce the overall size of the case. However, as long as manufactures insist on not making ANY cases without putting 5.25" bays in them, there are a lot of people who want something to cover up the ugliness these bays create. My ideal case would look just like the front of this without a door. The front sides would have vents/grills for pulling air in across all the drive bays and exhaust it out the back with vents/grills where they now typically have 9 expansion ports. Basically create a wind tunnel from front to back with the only compromise is not pulling air through the front panel for appearance reasons.
