Front
Overview |
|
|
|
| |
| Taking
a closer look at the front of this big tower case shows
that Corsair is using high quality materials. The front feautures a hairline brushed aluminium
finish. In the bottom part you can
find a coverplate behind which there can be a maximum of two 140/120
millimeter fans, where 140 millimeter ones have actually been pre-installed
(3 pin connector). The front I/O panel is located at the top. On the left
hand side there is the audio out as well as the audio in. Right next to
the audio connectors there is the reset button and in the center you
find the power button. On the right hand side there are two USB 3.0 as
well as USB 2.0
connectors. Right below the I/O panel you can find three 5.25 inch slots,
which are covered by bezels same aluminium finish you also get with the
cover plate. Overall the front looks very decent and one important reason for
that is the homogenous finish. |
Back

| Next
to the usual slot bezels, of which there are nine in this case, there is
another pre-installed 140 millimeter fan with 4 pin header, which has been placed right
behind the CPU cooler. Below the last slot bezel there is space
for an ATX power supply. Other than that Corsair provides their cases
with very decent screw threads, which make the thumbscrews fit
perfectly. |

Right side
Overview |

|

| Business
as usual, that's what you get when you have a look at the right hand
side panel. Its looks are really unspectacular and there are not even
vent holes. As soon as we remove the panel
things start to become a bit more interesting. The first thing we've
noticed, is the huge cut-out behind the motherboard. This allows you to
easily install a CPU cooler with backplate after you've put the
motherboard into the case. Furthermore there are numerous cable tie
loops which help arranging cables in a neat way. Looking for cable
routing holes reveals, that there are quite a few, which have been
positioned wisely. These holes have also been covered by rubber
grommets. Overall it should be easy to put together a very decently
wired build. Other than that the four snap-in cages for 2.5 inch drives
are very practical and can be found close to the front. |

Left side
Overview |
|
|
|
| |
A quick look at the left
side panel shows that Corsair provided it with a windows made from
acrylic glass. Once the side panel is removed, there is a clear view
at the interior, which is well arranged and not overcrowded. In the
bottom right corner there is space for six 3.5 inch drives, which have to
be mounted on carriages to then be slidden in place. Right above
there is some free space and there are also the two pre-installed 140 millimeter fans, which make
sure, that you can install even oversized graphics cards and that they
get plenty of fresh air. Again a bit closer to the top there are
three 5.25 inch bays. A closer look at the bottom left corner reveals the location where
you place the ATX power supply. The bottom of this case got a dust
filter, which makes sure, the PSU stays dust-free. Above the power
supply you can find the nine slot bezels as well as another
pre-installed 140 millimeter fan. This case offers enough space to
even house XL-ATX motherboards. Again the huge cut-out to install coolers with
backplate, even after one has put the motherboard in place, is clearly
visible. Last but not least there is the top. Here you can install 240
or a 280 millimeter radiators or two 120 or 140 millimeter fans. It's
also possible to put in a 360 or 420 millimeter rad or three 120 or 140
millimeter fans. We
decided to equip this case with a Corsair H100i all-in-on cooler, which
doesn't even block one of the 5.25 inch drive bays.
Once all the hardware is in place, you can see, that this case
offers plenty of space, even for an absolute high-end system and
custom watercooling builds.
Installing a dual radiator in the top as well as huge video
card wasn't a problem at all. Also cable routing can be done in a neat
way thanks to the various routing holes. |

Top
Overview |
|
| |
| As we've already
mentioned you find space to install either up to three 120 or 140
millimeter fans. Obviously it's also possible to install either a dual
or a triple radiator at this point. In any case, if you should decide to
populate this spot with fans or with a radiator plus fans, we recommend
to mount the fans that they move hot air out of the case. On the
second picture you can see the rubber grommets which help to reduce
vibrations. Corsair also put a dust filter in place, which sticks to the
case by magnets. |

Bottom
Overview |
|
| |
| The
bottom side of this case is quite unspectacular again. There is a
removable dustfilter which can be cleaned easily as well as four solid
feet with rubber coating. Other than that there is space for two 120
millimeter fans, if you remove the 3.5 inch cages. In this case you
could even install another dual rad here. |

Conclusion
| General |
|
+ |
- |
With the Obsidian Series 750D, Corsair managed to build a
big tower case with a well thought and spacious interior. In the top you
can for example place a triple radiator and when you remove the hard
drive cages, there is space for another dual radiator in the front or in
the bottom. Talking about the front, we noticed, that it's impossible
to install a 360 millimeter rad here. There are just about two to three
centimeters missing. We would have preferred to have this option but
only two instead of three 5.25 inch drive bay.
Overall the 750D offers a lot of opportunities. Regarding
the fans, we would like to see models with four pin connectors
everywhere and not only in the back. Apart from that it would be nice if
there was a simple fan controller, which lets users select between 5V,
7V and 12V.

- |
| Build quality with this case is on a
really good level. For example, Corsair didn't hopelessly save weight on
the side panels. Furthermore putting all the
components in place, is very comfortable, since there is plenty of space
everywhere. Very practical, that's what all the rubber covered cut outs
are, since you can route cables exactly where you would like them to.
Apart from that there is the huge cut out behind the motherboard, which
allows the installation of aftermarket coolers when the motherboard is
already in place.

| The Obsidian 750D is quite a big case but it isn't
gigantic like the 900D. The finish of the front is well done. We like its
looks, the hairline brushed aluminium plates give it a timeless touch. Overall the design is
very pleasing and the case
would look decent on, as well as underneath a desk. We would even go to
the point to say, that installing a 5.25 inch drive would ruin the looks
of the front. |
