The Define series is reaching new heights in combining stylish, contemporary design with maximum functionality and noise absorbing features. The minimalistic, yet stunning front panel design, fitted with noise absorbing material on the inside, creates an aura of exclusivity.

As the name implies, Define Mini is the smaller sibling of the acclaimed and award winning Define R4 case. Being a micro ATX version of Define R4, it offers a number of interesting functions with a very stylish appearance. It's a case focused on low noise level, without neglecting other important features such as cooling, expandability and ease of use. The Define Mini excels in including a lot of features in a small size!

The patent pending feature ModuVent™, in which you can choose whether to have fan slots in side and top panels open or not, makes the case appealing for users seeking optimal silence, as well as the performance hungry ones.

The sleek black interior is matched with pre-fitted, dense noise absorbing material on the side panels, efficiently absorbing noise and vibrations. You can fit an astonishing total of six hard drives into this case, using the user friendly HDD-trays. All painted in a nice white color and using black silicone mounts. PSU is mounted in the bottom of the case, with a convenient pull-out filter beneath it.

1 out of 5 eggsIf contact is important to you...

Pros: see other reviews

Cons: Two form-submitted contacts to Fractal in three days went unanswered.

Other Thoughts: It can be the best case in the world, but if Fractal refuses to respond to questions, it has no value to me.

5 out of 5 eggsExtremely Nice Case

Pros: The build quality of this case is unlike any other I have seen. I managed to snag one while it was on sale and got it for a steal. Even at full price though its really worth it. The case feels sturdy and well designed. No sharp edges and the hard drive bays can be removed very easily. I have a GTX 780 2 fans and a H80i water cooler and I can not hear the computer under my desk over myself typing on the keyboard... It really is as quiet as they say. Every panel is covered in Sound dampening material and even the fan slots come covered incase you dont use them.

Cons: None at all. I loved the case the second i opened the box.

Other Thoughts: You would not do yourself wrong with buying this case. Fractal has forever earned my respect with the extreme build quality of this case and when ever i upgrade my computers from now on they will be the first place I look for cases.

5 out of 5 eggsAmazing Case

Pros: - Minimalistic appearance.
- Brushed-look front panel is really nice.
- Great cable management.
- Almost all black except for HDD/SSD quick release trays and PCIe brackets.
- Lots of options for hard drive and fan placements.
- Silent.
- Fans that come with the case are pretty good.

Cons: - Flimsy drive bay covers.
- Bright LED

Other Thoughts: Build quality is okay. The foam sound insulation for one of the "ModuVents" was glued on crooked like one of the workers was having a bad day and just slapped it on. Not worth taking off an egg but worth mentioning. Besides that fact I think this case is amazing and it's a great buy if you are looking for a silent and sleek looking PC.

5 out of 5 eggsI feel spoiled

Pros: So simple and elegant look.
Easy to work on, lots of options.
Love the room for extra fans if needed. Front fan mounts was a great idea.
Just purchased this about 3 weeks ago and loving this case.
Coming from what I though was a decent 10 year old case to this one really makes me realize how others tell the difference between a cheap case to a good one. This one is a Great one. Was not expecting such a sturdy case.

Cons: Heavy. Weight description is accurate. Be aware.

Got a restocked case, saw all the tape around it and was afraid of something gone bad. Got lucky and was only the front/top panel USB 2.0 port connection, I put it back in place in no time.

Not dropping an egg over poor judgement, but something to keep in mind.
I work on manufacturing, here is a hint Fractal and Newegg; always check your returned items for defects.

Other Thoughts: Just had to replace my 10 year old computer and wanted a case that can take a beating and had filter options.
Was afraid of the price tag (that's on me, I am cheap), but once I got it out of it's box I felt in love with it.

Thank you Fractal, and Newegg of course.

5 out of 5 eggsGreat overall case

Pros: The case has plenty of space. The noise padding does a pretty good job dampening noise. Design and quality is great.

Part of the harddrive bay is removable to accommodate long PCI cards.

The filters on this case do a good job of keeping out dust and pet hair.

Cons: While it is a great overall case there are a few issues I've run in to. While the majority of the case is made from the matte metal, the front panel of the case (enclosure where the front usb ports are) can pop off if you accidentally bump it hard enough. When that happens the short USB cords can get unplugged and it's a pain to get back.

The dust filter on the bottom of the case is removed by the back. This is particularily annoying since my computers are close to walls and you can't remove the filter unless you move the case.

Other Thoughts: This was the third Fractal case I bought (the others being the R4 and XL R2).

LED light is really bright, especially when it blinks when the computer is in low power.

I bought a Hyper 212 cooler to put in, and that fit in without any issues.

This is somewhat of a con, but one of the Fractal fans it shipped with made a horrible scratching noise when it would spin up. I contacted Fractal and within a day they had already shipped a replacement fan, free of charge. From my experience their customer service has been nothing short of excellent.

2 out of 5 eggsBe warned.

Pros: Looks great, really quiet.

Cons: So. When my computer goes to sleep the fractal case has an led light on the power switch that blinks the entire duration of the hibernation. IN my case ALL NIGHT AS IM SLEEPING. i've resorted to putting black electrical tape on the power switch. I really shouldn't have to do this at all. This is a huge huge downer for me ... why have an led blink a bright blue light ALL night especially when most people don't shut their computers down anymore... i looked on the forums people have resorted to dismantling the led light and taking a sharpie to it and other creative solutions... inother words you can find another case for your money that doesn't annoy the living hell out of you.

5 out of 5 eggs

Pros: Nice, slick design. Sound padding is well thought out and effective. Versatile, can even remove one hard drive block for larger video cards or even to turn it sideways. Room for liquid cooling: I used a Corsair H60 mounted at the rear fan port. Optical drive slot cover mechanisms are very neat, wish every manufacturer used this design.

Cons: Power LED is a super bright blue: distracting for watching HTPC stuff in dark rooms, so I unplugged it. Included fans are ok, but are a bit noisy (more of an audible whoosh than an actual whine, so not that bad) at normal speeds. Included fan controller is very cheap: tiny blobs of glue used to keep it together fell apart, making plugs fall out (plugs are very loose and don't stay in by themselves, so glue is necessary). Nothing worth dinging an Egg for, just observations.

Other Thoughts: Wish it had more than one front USB 3.0, but not a big deal. Fractal makes good stuff.

5 out of 5 eggsFriggin Sweet Case

Pros: This case is hands down the best mid tower case I've ever owned. I've got my current gaming rig in it cooled with noctua fans. Using a decibel meter, this case was quieter than a friend's case which is using water cooling

The wire management in this case is top notch, the drive trays are of solid metal design that have holes to attach a SSD, and the quick locks in the 5.25 bays really keep a solid grasp on on the bluray drive.

The inside of the case fit a 770 GTX without any issues, and if there were the middle drive tray is removeable to allow for larger videocards.

Cons: Some might be surprised by the size of this case. It's very close to the same length as a full sized tower, but it is much shorter. Over all, it still saves space while not making system building a pain.

One other thing i noticed, the case doesn't do a good job dampening mechanical hard drive vibration. It's not a deal breaker by any means. It just took me a while to figure out what that very light vibration was on my desk!

Other Thoughts: I highly reccomend this case for a gamer that wants a quiet case that will cut back a bit on space. It's not a shuttle case by any means, but it will still cut back on space usage.

3 out of 5 eggsDisappointed

Pros: Silent, great price, very sleek and stealthy.

Cons: Included fan controller DOA
Sound dampening material coming off or sagging
Backing plate cut-out is too small

Other Thoughts: I want to start this off by saying that I am a huge fan of Fractal... I own the full sized Define R4 for my home computer and another Mini R4, which both were great.

That being said, this case shouldn't have left the assembly line. The sound dampening material is falling off, fan controller was DOA, power button isn't seated properly, and the general feel of the case is chintzy. Also it should be mentioned that the cut-out for the motherboard tray isn't large enough to accommodate aftermarket backing plates, I had to cut off 1/4" in order to access the screws.

Sadly, this will be my last Fractal purchase for the above mentioned reasons.

5 out of 5 eggs

Pros: Love this case
Great spacious design
Lots of room
Removable hdd cage

Cons: can get a little messy for cable management but not a huge deal

Other Thoughts: Buy this case, make sure if your adding in fans you get quiet fans. The ones that they ship with it are wonderful, but the one i bought sounds like a lawnmower. Just make sure to get quiet fans and you wont be disappointed.
