SilverStone’s Sugo line started off as a series of stylish but compact microATX
cases, with the first two models emulating the shoebox design popularized by
Shuttle before moving onto more traditional towers with the third and fourth
variants. The SG05
and SG06
went back to the shoebox style, leveraging the growing popularity of the mini-ITX
form factor. Up to this point they were all conservatively designed, particularly
with regard to cooling.
The superb SG07/SG08
took their game to another level, high-end models that offered enthusiast class
features in a much sleeker package than clunky towers. The keys to success were
a full-sized ATX power supply embedded at the front of the case, a giant fan
blowing down from the top, enough room for a reasonably good CPU cooler, and
support for long dual slot graphics card. The SG09 follows in this mold, attempting
to recreate the same magic with the larger micro-ATX form factor.

SSDs are highly recommended in place of hard drives. * Maximum length for PSU is 180mm, we recommend 160mm due to varying connector locations on PSUs and the unique structure of SG09. We do not promise that all retail PSUs on the market can be installed in the SG09. Please refer the guides provided in this manual to select your PSU. |
A look at the specifications of reveals some interesting tidbits. A typical
SilverStone case has an easily recognizable brush aluminum front bezel that
gives it an air of sophistication and quality but the SG09’s front panel is
made of “cheap” plastic. The case shares some attributes of the smaller
SG07 — a front-mounted power supply and slim optical drive bay to reduce
the overall height, and a large 180 mm Air Penetrator fan at the top blowing
downward. Fan support in general is surprisingly generous with an additional
two 120 mm fans on the rear and side and up to three extra 80/92 mm fans can
be added. Finally, the CPU cooler clearance is almost the same as a typical
tower — all signs point to an even better SFF gaming chassis.
The box. |
The case. |
If not for the logo at the front, you’d be hard pressed to recognize it as
a SilverStone product. Priority has clearly been given to airflow over aesthetics,
making the SG09 quite unsightly compared to most Silverstone cases. The front
grill has an unusual shape and wide gaps that clash with the honeycomb vents
utilized almost everywhere else. The streamlined design of previous Sugo incarnations
is gone due to the external dust filters at the top and sides, and a protruding
power supply intake vent. Ona more positive note, the SG09 stands less than
a foot tall but the accommodations inside aren’t too different from a larger
case using a more traditional layout.
Accessories. |
The goodie bag has quite a few fan accessories including adapters to replace the 180 mm top fan with a 140 mm model, a three-headed 3-pin to molex fan adapter, and a soft adhesive frame to create a duct between an optional 80 x 25 mm fan on the right side and the side panel. There are also spacers and a bracket to facilitate slim optical drive installation, a few cable ties, an internal USB 3.0 to 2.0 adapter, and a set of rubber case feet with adhesive which have to be attached by the user.
The Sugo Pack. |
For serious gamers, SilverStone also offers a carrying bag that makes lugging your gear to LAN parties a bit easier. The Sugo Pack is designed to fit every variant of the Sugo line as well as the GD04/GD05, ML03, and FT03/FT03 Mini.
Some room to spare with the SG09 strapped in. |
It retails for about US$45 and it’s well suited for its purpose. The Sugo Pack is strong, with plenty of padding and numerous compartments for storing keyboards, mice, cables, and other miscellaneous accessories.
EXTERIOR
The Sugo SG09 measures 22.0 x 29.5 x 35.4 cm or 8.7 x 11.6 x 13.9 inches (W
x H x D) for a total volume of just 23 liters, substantially less than most
microATX towers, which fall in the 30 to 35 liter range.

INTERIOR
Like previous Sugos, the SG09 has good overall build quality. The internal
frame feels quite sturdy and the exterior panels are 0.9 mm thick, just enough
to avoid feeling cheap.

ASSEMBLY
With its small size, we expected assembly in the SG09 to be tedious, but as
the drives and power supply mount from the right side, we didn’t encounter much
difficulty. We do recommend you plug in front panel connectors before mounting
the board as it is hard to reach in afterwards.

Stock Fan Noise
The Sugo SG09’s stock fan configuration includes a 180 mm top intake fan and a pair of 120 mm fans, one acting as an exhaust at the rear and other as an intake on the left side, near the front. The three have different acoustic characteristics however.

Fan Voltage | Top | Rear | Side | Combined |
12V | 36 | 25 | 29~30 | 37~38 |

Low (5V~6V) | 22 | – | – | – |
5V | 16 | 13 | 15 | 20 |
Measuring mic positioned 1m at diagonal angle left/front of case. |
The top fan is the loudest and produces a low-pitched rumble at 9V and above but smoothes out at 7V and below. At lower speeds we also noted a ticking sound close up. It’s equipped with a two speed switch, with the low setting corresponding to somewhere between 5V and 6V. The side fan is quieter and has a very benign sound. The rear fan is quieter still but it has a dry, droney character that is more similar to the top fan than its 120 mm compatriot.
Together, the three fans generate an fairly inoffensive sound with little noticeable tonality.
TEST RESULTS: AMD Radeon HD 5450
Our first test configuration features a low power passively cooled graphics card, a Radeon HD 5450 so it’s representative of a non-gaming PC with a reasonably powerful CPU. A discrete card also gives us an extra temperature data point from an additional location within the case.

We began testing with the case fans turned off to create a baseline. The system was fairly quiet in this configuration, measuring 18 dBA@1m. We could feel the hard drive vibrations on the right side of the case but it wasn’t transmitted elsewhere and was only audible at close proximity; otherwise the machine sounded smooth. The CPU got quite toasty without any assistance, hitting 76°C while the GPU stabilized at 69°C.
Turning on the system fans with just 5V had an interesting thermal effect.
As one would expect, the noise level increased and CPU temperature lowered by
a sizable amount, but the GPU temperature actually increased by 2°C. Flipping
the top fan to act as an exhaust resulted in a dramatic improvement in overall
temperatures, verifying our intuition that using the top fan as an intake interferes
with GPU cooling. This reversed fan orientation was also slightly louder but
well worth the massive 17°C improvement in GPU cooling.

Even with the top fan flip, the SG09 performance fell well behind larger microATX
cases. The thermal and acoustic results we generated using our HD 5450 test
configuration were poor, bettered by several previously tested microATX cases.
It was only really competitive with the SilverStone
Precision PS07. The more popular SilverStone
Temjin TJ08-E, Fractal
Define Mini, and Lian
Li PC-V354 were all superior.
TEST RESULTS: ASUS EAH6850 DirectCU
To simulate a more demanding gaming system, our second test configuration uses an HD 6850 graphics card from ASUS. The 6850 uses about 100W more than the 5450, creating a hotter, more stressful environment.

Swapping out the HD 5450 for a HD 6850 had only a minor effect on acoustics,
increasing the noise level by 1 dB and giving it a slightly rougher sound. On
load, a stable 90°C GPU temperature was established with the system fans
at 5V and the GPU fan manually set to the same speed as the automatic setting
when idle. Increasing the speed of the top fan to 7V gave us better cooling
across the board, allowing us to slow the GPU fan to 1460 RPM; the noise level
was a steep 4 dB higher however. Speeding up the rear fan to 9V instead was
only marginally better, but it had a more bearable acoustic cost of just 1 dB.

The SG09 fared much better with a HD 6850, surpassing the Precision PS07 in both CPU temperature and noise level. It still had a sizable deficit in CPU cooling compared to most of the other cases compared however.
AUDIO RECORDINGS
These recordings were made with a high resolution, lab quality, digital recording
system inside SPCR’s own 11 dBA ambient anechoic chamber, then converted to
LAME 128kbps encoded MP3s. We’ve listened long and hard to ensure there is no
audible degradation from the original WAV files to these MP3s. They represent
a quick snapshot of what we heard during the review.
Each recording starts with ambient noise, then 10 second segments of product
at various states. For the most realistic results,
set the volume so that the starting ambient level is just barely audible, then
don’t change the volume setting again while comparing all the sound files.

FINAL THOUGHTS
With the Sugo SG09, SilverStone mixed elements of the SG07
and Fortress
FT03 in its design, resulting in one of the most interesting case we’ve
examined all year. Producing a 23 liter microATX tower while maintaining support
for most enthusiast components (tall CPU heatsinks, long graphics cards) is
an impressive feat, and in classic SilverStone fashion, they took advantage
of every square inch available to them. Performance was also fairly good considering
the size of the chassis, though there is plenty of room for improvement.
The biggest mistake was positioning the big 180 mm fan at the top as an intake
but thankfully it’s an easy fix. Having a significant amount of air blowing
down is seriously detrimental to video card cooling, preventing hot air wafting
up from the GPU from dissipating through the rear exhaust. Keeping dust out
with positive pressure is nice but we gladly traded that luxury for improved
cooling and lower fan speeds. There are other details that could use some work.
The hard drive mounting system does little to dampen vibration though it isn’t
passed onto the side panels, etc. The power supply mount could be sturdier and
cable management are needed.
On a more superficial level, the case is surprisingly ugly. The exterior is
very busy, flying in the face of the usual sleek SilverStone aesthetic. The
front grill looks cheap and the external dust filters protrude noticeably from
the rest of the case. Having three fan placements on the side also seems excessive.
The split cover design provides some convenience but adds a screw and an unattractive
long line running across the left side of the case.
Despite its deficiencies, the SG09 deserves consideration if you’re in the
market for a SFF gaming case with a bit more versatility than your typical mini-ITX
fare. This larger chassis has several advantages, including more expansions
slots (and even the possibility of dual graphics cards though we wouldn’t recommend
it in such a small case), a big CPU cooler, and more storage.
Our thanks to SilverStone for the Sugo SG09 case sample.
