Fractal Design Define R4 Black Pearl Mid Tower Ultra Low Noise Performance Case USB 3.0 with Silent 140mm Fans is rated 4.9 out of 5 by 24.
Rated 5 out of 5 by from Great but take care when fitting SSDs I fitted the SSDs below the motherboard as designed but power leads do not fit as the SSDs are too close to the metal. This is a pain as the SSD fitting screws are covered by the motherboard. My advice would be to fit below motherboard but use velcro rather than the screws provided. Apart from that the case was a dream to work with.

Rated 5 out of 5 by from Chunky, quiet, great routing There's no denying this is a big case, so you'll need a decent amount of space under your desk. However, it provides plenty of space for a full-size motherboard and loads of components. The cable routing is excellent, enabling me to do the tidiest job ever. The drive bays are a breeze and very flexible. Sound insulation is definitely superior. All told, a delight to use.

Rated 5 out of 5 by from Solid Silent Quality Case This was the case of choice for a graphics workstation, for its' silent operation and robust quality. This case is heavy, and will take future upgrades for many years, The internal flexibility, allows for easy removal and re-arrangement of drive bays to facilitate low noise and low speed cooling. Cable management is easy, and SSD placement ample. Looks fantastic in an understated way, cost reflects the quality of design and build.

Rated 5 out of 5 by from Simply the best case I've ever used It's difficult to know where to begin, so I won't go into details. Look on YouTube and there are plenty Fractal Design Define R4 (and R5) case reviews/builds. I really cannot fault this case. The flexibility is enormous. The build fantastic. Cable management extremely well thought out. Sound deadening and quieting features work really well. And its price: how on earth do they do it at this price? It oozes quality at every turn, is a pleasure to build into, and its great value too. What more could you ask for?

Rated 5 out of 5 by from Great case This is a great quality case - solid, cool and quiet. Very easy to work with too.

Rated 5 out of 5 by from Very good, although had a small issue. I love this case. For normal use the noise is on par with my old Lian Li case (minus the annoying rattle and hum after 6 years). However when gaming the graphics card fan is dramatically reduced in volume making the entire experience even better. This case has a really HEAVY solid vibe, a serious quality product that does well to reduce noise. One negative point for the one I received, the threading on the left side panel's top screw area was not working. So I have had to remove the top screw. Everything else is perfect and since I have thrown out the old case I am not going to spend time dissecting my system again just to RMA my only case over one of the side panel screws not working. Even with the screw removed, the side panel is very secure and not going anywhere and there is no rattle or hum EVEN with that screw missing now.

Rated 5 out of 5 by from Great case! Excellent case, very quiet and very nice to look at.

Rated 5 out of 5 by from Great Custom Build Case This is one of the easiest case's I've worked with, built a system for a friend who knows nothing about hardware...bit of a waste really. It is well thought out, well made and everything has been considered to make it a dream to put together. Only down side might be the size of's a beast! but justifiable if you want your case to be uncluttered by cables and have the best airflow you could ask for.

Questions & Answers

Hi Will the corsair H100i Extreme Performance Water cooler fit into this case

I would like to fit a Corsair H100 1 Extreme Performance cooler into the R4 Fractal Design Define case is this possible
Asked by: jackace
I have built with both these items but never at the same time, the H100i is a fairly compact cooler , which I have fitted into an NZXT 340 , a much smaller case. The R4 is sized for a top 240mm rad so this should be fine, but I have not actually combined the two.

Will the Nzxt Kraken x60 fit in this case?

Asked by: KennyB
This case has a 240mm top slot available and the X60 is 280mm so the official answer is NO. It is possible to remove the drive bays to free up a space on the front, but this may or may not be OK. Your best bet is to get the Define S which will certainly fit this rad.

Asus Maximum VII Ranger + Corsair H100i

Has anyone installed this motherboard & CPU cooler in this case? Any issues? Thanks to other response regarding installing fans AFTER connecting power by the way, I'd have assembled the cooler then struggled ;-)
Asked by: AirZeee
I do not know anything about that particular motherboard but what I want to share with you is, the space in this case is vast. Plus you can remove the upper drive tray for even more space. I highly doubt you would have any issues installing practically any consumer/prosumer/gamer motherboard.

Will the quiet! Shadow Rock SLIM fit?

Will the "be quiet! Shadow Rock SLIM" (LN55602) fit in this case properly? This is the case I plan on buying soon and eventually I would like to get a new cooler for the CPU to keep my current CPU cooler, better, while providing future proofing in case I can get an ugraded 125W CPU.
Asked by: techwg
This will fit a cooler up to 170mm with no side fan fitted, the SR Slim is 161mm tall so yes.
