DEFINE S

The Fractal Design Define S lends the appearance, sound dampening technology, and support for a wide variety of components from the widely popular Define Series, while introducing a new, innovative internal layout. The Define S case is packed with intelligently designed enthusiast-oriented features delivering a silent case with powerful and expansive air and liquid cooling support, presented in a stunning Scandinavian inspired construction.

The modernized internal layout of the Define S omits the optical drive bays, instead focusing on a clear straight airflow path and uncompromising water cooling support.

The best case I've ever used

Pros: -Cable management is really easy in this case
-Moving the drives behind the MB opens up tons of space in the case and improves airflow
-Plenty of space for fans and/radiators
-Very quiet case fans
-Quality construction
-Cheaper than many cases that are of inferior design

Cons: Not really cons for me but might be for some people
-Not a lot of space for internal drives
-No mounts for internal CD/DVD/Blu-ray at all

Other Thoughts: I've been using this case for almost a year now and at this point, barring it being lost or destroyed in a move or something (in which case I would buy this case again), I can't imagine ever buying another computer case. I love it that much.

great box.

Pros: It’s a beautiful case and looks great. I’ve had mine for 2.5 years now. Wide open insides, easily opening sides left and right. Makes for easy upgrading.
3 dedicated ssd spots.
I have a top mounted dual fan liquid radiator and this case is perfect for airflow.
Sound dampening on the sides of the case, if you’re that sensitive.

Cons: I haven’t mounted a drive beyond the 3 ssds. It looks like it may take some jury rigging with a 3.5 adaptor. So if you require a lot of disk space, you might have a problem. I don’t know.

Other Thoughts: A windowed side was an option when I first bought mine. I should have bought the windowed version. I don’t think the sound dampener pads really do much.

more roomy than you think

Pros: can fit 5 drives either: 5x 2.5 in drives, or 3x 3.5in and 2x 2.5in drive configurations.
has enough space to happily cable manage even the thickest of 24 pin cables
has pre-built water cooling support mounts for pumps and reservoirs

the no-window version can hold 9 fans, 140 or 120mm, so not just a great water cooling case, but a great airflow one too

Cons: wish the top vent system came with dust filters, and wish the vent cover could break in two to cover the unused portions
for the non-windowed version, wish the side-panel fan position also had a dust filter.

Other Thoughts: mine came with a bad front audio jack and Fractal Design is sending me a replacement to try and fix the issue.

Good case but no place for DVD/BR

Pros: Very well made case.

Cons: No CD/DVD/BR mounting option. If you want to use any kind of CD/DVD/BR you will have to buy an enclosure and hook it up to the USB.

Other Thoughts: NewEgg should disclose that there is no way to mount a CD/DVD/BR in the description.

Great case with plenty of room!

Pros: Has plenty of Space to work with
Nice sturdy build
2 dedicated SSD slots & 3 HDD slot

Cons: Paint was came off easily while just

Other Thoughts: Other than some of the paint coming off while screwing in some of the screws I am absolutely in love with this case. It was my first build and it had more than plenty of Space for me to work with. I got it on sale for $50 at the time and I feel like the money was well spent.

Great case with one MAJOR flaw

Pros: -nice looks
-simple design
-easy to build in with good cable management

Cons: -The 3.5 inch mounting solution is a bit awkward with connecting the power/data cables.
-the biggest con of this case is the lack of sound dampening on the front of the case.
-I have 3 drives installed and only the default 1 fan in front and my computer vibrates so hard i can hear the humming from 4-5 feet away right now. The whole case just seems to hum and it's very annoying...

The biggest little midtower there is. Nothing anywhere near the price range can compete.

Pros: Well thought out dimensions. It is deeper and wider than the full tower it replaced while requiring less space.
The side panels are heavy duty. They alone weigh more than my previous case.
Quiet, cool and spacious.
More room and options for cable management than anyone could need. My first case without a bulging side panel.
Not having a stupid window is cheaper and quieter with the solid panel. Win-win.

Cons: Despite the description of it as a "steel mid tower" with a "solid front panel" and the omission of the acronym "ABS," the front bezel is entirely plastic with a brushed appearance.
The bottom fan mount is blocked by modular PSUs.

Other Thoughts: I can see using this case for a long time. A clean, classy, and understated appearance never goes out of style. It's solidly built with room for nearly any kind of hardware and water cooling configuration.

Well built, sturdy and lots of room

Pros: Pros: Tons of room for easy building and cable management.
Lots of areas for radiators(of varying sizes) and fans.
Several removable dust screens and panels for extra ventilation/airflow.
Well built; feels very sturdy and reliable.
Things run very quiet inside if you have all panels and dust filters on.

Cons: Nothing I can think of; this was a much better and easier building experience than my previous chassis, an NZXT Source 210 elite.

Other Thoughts: Quite heavy!
