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.

5 out of 5 eggsExcept the Light!

Pros: - Looks nice
- Fairly small
- Easy to work with
- Nice cutouts for cables & heatsink backplate
- Flexibly ventilated
- Quality fans
- Flexible configuration

Cons: This case has a huge, blinding Power LED light. It's bad enough when the machine is just in a normal On condition. But, my motherboard (and Asus boards, in general AFAIK) flash that LED in Sleep mode. The first night I had the case, I thought some Emergency Services people were coming to pick up another one of the neighbors. The blindingly bright flashing was visible across the house. Because the LED is encircles the power button and then arcs down to the front of the case, you can't even put tape over it to mask it. It's either unplug the LED from the motherboard or turn the machine off at night.

Other Thoughts: Except for the LED noted above, I'm very happy with the case. I try to keep my computer as quiet as possible. This case allows that. For normal activities, it's almost silent. But, if you want to put a lot of high power stuff in the case, you can add quite a few fans to it very easily. Plus, even though it's a fairly small case, there's a lot of room inside. I've got an "ASUS STRIX-GTX970-DC2OC-4GD5 GeForce GTX 970 4GB 256-Bit GDDR5 PCI Express 3.0 SLI Support G-SYNC Support Video Card" in it and that card is huge (11 inches long). It's a very versatile, high quality, fairly inexpensive case.

5 out of 5 eggsSilent as promised

Pros: This case is definitely quite silent, compared to some of the other cases I've had before. Most of the sides are cushioned...which seems to be what keeps the noise level low. It's also very spacy for a case.

Cons: I thought it would be "micro" in size, but it actually feels like a mid-size case. A bit smaller case would be nice.

5 out of 5 eggsNice case

Pros: Solid build. Plenty drive bays. Excellent case and CPU cooling capabilities. Styling is very good.

Cons: The only con I came up with is that the entire front panel comes off pretty easy. With the way the cables are snaked through the chassis the connections to the front panel plugs they unplug and you have to open the case, unplug the onboard connectors and give yourself enough slack to plug them back into the front panel again. This should have a clip connector on it so it only comes off when you want to take it off (for cleaning)

Other Thoughts: This is not a micro sized case. It is a case for microATX boards. It has six drive bays are perfect for my MS Home Server RAID array. With the sound deadening construction and multiple cooling options makes it a good choice for this.

5 out of 5 eggsExcellent case, but not quite "mini"

Pros: - Very quiet. I can hardly make out the sound of my GPU and CPU fans when the case is closed.

- Attractive minimalist design. Fits in with almost any room's aesthetic very nicely.

- Two front USB 2.0 ports, one front USB 3.0 port. People complain about the lack of 3.0 in the front, but I think 3 ports on the front of a minimalist case is pretty generous in the first place!

- Spacious interior. I had more than enough room for my three hard drives, GTX 770, aftermarket cooler, and an extra case fan.

- Easy installation, though not completely tool-less. You'll need a screwdriver or two.

- Included fans are effective and match the aesthetic of the case, though they could be quieter. I replaced the rear fan with a Noctua from my old system and it made a very audible difference.

- Good cable management, but a couple of my power cables are a little too thick to route. No big deal unless you're a perfectionist. The case comes with a few zip ties, which is a nice touch.

- Very sturdy. This case is quite solid and has a premium feel. Unfortunately, this ties in with my biggest con...

Cons: - HEAVY. This thing weighs about 20 lbs when it's completely empty. My mid tower is lighter than this case. It doesn't help that there isn't really a good place to grip it - there's a set of filters on the underside of the case that slide and rattle when you grab them making it almost impossible to comfortably pick it up. Fortunately, I don't travel with my PC, and I rarely need to open up my systems, so it isn't a huge issue. However, it's definitely something to keep in mind if you're planning on rearranging your workspace or you move around on a regular basis.

- The included fan controller is of sub-par construction. The wires are very exposed and appear to be attached to the card with a questionable blob of hot glue. It uses an ugly 4-pin molex power connection, which had two severely bent pins straight out of the box (hardly a rarity - molex is not exactly the pinnacle of design). I was, however, able to get it running, and it works well enough. No eggs lost, but I'm considering buying a different controller.

- Airflow could be better. The case has a door on the front that looks nice but blocks the intake fan. If you use a fan in a different location (of which there are several - another plus!) it won't be a problem.

- Power LED is shockingly bright. I had to unplug it so it didn't blind me at night.

Other Thoughts: If you're looking for a compact system, this is not the case for you. It's fairly large and very heavy. However, if you just want a quiet, cool, minimalist case, I can't recommend this enough. It's the nicest case I've ever owned, and its few flaws are easily corrected. I'll definitely be buying another Fractal in the future!

4 out of 5 eggsNot Mini- not even a little

Pros: The first thing you will notice when you open this is that it is a veritable tank of a case. It weighs more empty than my entire computer that I am writing this on that this build will replace. It is deeper and wider than the NZXT Gamma I am using, thought the Gamma is a couple inches taller.

Each side panel weighs approximately four pounds by itself. Each is covered in a dense rubber pad to dampen vibrations.

The case has room for 6 case fans; it comes with 2 good 120mm fans and a fan controller specifically designed to go in the recessed perpendicular expansion slot. The front and bottom fans(including the PSU's) are covered by dust filters. The preinstalled fans come in the rear(exhaust) and top front(intake.) There is room for a second front 120mm; a bottom 120mm intake(which would be blocked by a long power supply) and two spare 140/120mm fan ports on the side door and rear roof of the case. These 140mm slots are initially covered by what FD calls ModuVent: foam-backed plastic covers to block noise and keep your airflow from getting chaotic from the open vents. This case is good for a pressure-conscious fan setup(positive or negative pressure.)

The top 5.25 bay and middle 3.5 rack are removable with thumb screws. The middle bay will need to come out for large video cards, but a small one like a 750ti should fit perfectly without removing it.

There is good space behind the motherboard, large, ample grommets, plenty of anchor points, all you need for perfect cable management.

This case thankfully lacks the edgy, immature "1337 g4m1ng C0mpu7r" design style that mostly defined the last decade of this hobby. It looks clean, professional, and minimalist thanks to its brushed aluminum-patterned front door, and single, leering LED eye. Inside it has the same smooth black, including black mounting hardware, and a little bit of white contrast, in the drive sleds and slot covers. This case wouldn't look out of place anywhere- on the desk of a CEO, a server room, a home office, or in a gaming den. Combined with it's weight, I think its hostname will be Monolith.

Cons: Not suitable for an SFF PC, HTPC, portable LAN machine, or other lightweight task. Lightweight is not in this item's vocabulary, it has never heard of lightweight. They really shouldn't have named it Mini. It's not. At all. Maybe compared to a HAF X.

The moduvent covers are nice, but it doesn't come with filters to use if you do choose to install fans in the top or side hardpoint.

Only one USB3.0 port up front

No HDD indicator light

The front panel LED may be too bright for you, and would be inappropriate for a room someone will sleep in(studies show blue light disturbs sleep the most)

Fan controller seems a bit flimsy internally, and is unfortunately the only thing in my entire system which calls for a 4 pin molex connector, the only thing that is brown, the only unsleeved cables; the power cable from it is long enough to stow the connections behind the motherboard at least. I wish they would have shrinkwrapped the cables on it.

The internal padding, judging by the smell, is made from recycled asphalt; it may put off chemicals. Doesn't bother me much, but some people are sensitive to such things.

The front bezel's design severely restricts airflow to the front intakes. The door could use some extra vents, angled down of course to reduce noise.

Other Thoughts: Overall, I think this case is going to work out perfectly.

5 out of 5 eggsFine case

Pros: Sound dampening is good. HDD vibration dampening trays are great. Fans are good. Rubber holes for passing cables behind the mobo are good. Build quality, metal thickness, and overall heft are good.

Cons: The screw holes were tapped, and then the case was painted black, resulting in paint in the screw holes. This means you need a screw driver to get a thumbscrew into a hole for the first time; after that, you can operate them by hand. This was a problem with the optional screws used to secure the drive trays.

Should include three 120mm fans at this price.

Should be 2 USB3 ports on the top since it uses an entire USB3 header on the mobo which supports 2 ports. It's wasting a port.

Should be more space behind the mobo tray so you can hide wiring there. Right now I had to jam the side panel on there so all of the wiring could fit.

Other Thoughts: I moved the fan in the back around to the second spot on the front, and got a more powerful fan for the back, so the two fans blowing in at the front would be matched by a single fan blowing out in the rear. Keeps six hard drives cool.

4 out of 5 eggs

Pros: Very quiet. Easy to work inside case - well laid out.

Cons: Side panels difficult to remove/replace unless you have the case laying on its side and have plenty of room around it. One standoff broke during installation.

Other Thoughts: What will happen if I click eject when the front is closed?

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.
