We are currently living in a digital golden age with easy access to many different forms of high definition media, not to mention affordable devices for producing our own. Though the rest of the traditional PC market is shifting toward more portable hardware, mass local storage remains a constant and ever present need. As a result, home servers and network storage devices continue to garner much interest. Recently reviewed server systems like the HP ProLiant MicroServer Gen8 and QNAP TS-469L make strong arguments for pre-built machines, but for some, the fully customized DIY option is ideal.
One of the biggest issues with the enthusiast server solution is case selection. Most mini-ITX enclosures aren’t specialized enough for one specific application like storage as manufacturers tend to prefer more profitable products with a wider audience. A chassis may include four to six drive bays, qualifying it as server-friendly in the eyes of a marketing team, but more often than not this is an afterthought rather than a core feature the case is built around. The product we’re looking at today goes against the norm.

The SilverStone DS380 reminds us somewhat of the Chenbro SR30169, a small server case with four hot-swap bays we examined a few months ago. The SR30169 serves the same basic function, providing compact removable storage, though it features a completely different (and incidentally flawed) internal design. It has similar proportions, though the DS380 is almost 30% larger in volume, mostly due to its depth. The extra space expands its functionality dramatically though — the DS380 has horizontal front-accessible drive bays stacked from top to bottom, eight in total. It also has more cooling, in the form of three 120 mm fans, two on the side blowing over the drive area, and one at the back acting as exhaust, and there’s room inside for a good-sized heatsink as well.

The DS380 ships with a basic manual, a bag of screws, a pair of keys, a long case badge for the door, a plastic contraption for holding up a long graphics card, a plastic hook to help route cables, and some labels for the removable drive caddy covers.

EXTERIOR & COVER
The DS380 is composed of an brush aluminum front door affixed to a thick plastic bezel and a sturdy steel body. It measures 21.1 x 28.5 x 36.0 cm or 8.3 x 11.2 x 14.2 inches (W x H x D), giving it a total volume of 21.6 Liters.

INTERIOR
The interior of the DS380 is fairly well built but the drive cages aren’t as secure as we would like. The hot-swap cage is big and heavy but is only held on by six screws, four at the side and two at the bottom. The smaller 2.5 inch cage hangs down from the top panel, completely unsupported at the bottom, which isn’t a problem if you’re only using it to house SSDs.

ASSEMBLY
Assembly of the DS380 is fairly straightforward but the spacing inside is incredibly tight — exercising some forethought is highly recommended. In particular, plug in all the connectors that will be positioned at the bottom and rear of the case before mounting the motherboard itself, as it will be very difficult to access them later on. In our case, pre-connecting the 4-pin AUX12V plug and all the SATA cables saved us a lot of trouble.

Test Drive Noise Summary | ||
Drive | Vibration 1-10 (10 = no vibration) | Idle Airborne Acoustics @1m |
Seagate Barracuda XT 2TB | 7~8 | 17 dBA |
Samsung F3 EcoGreen 2TB | 7 | 15~16 dBA |
WD Caviar SE16 320GB | 6 | 18~19 dBA |
WD Red 3TB | 9 | 13~14 dBA |
Usually we test cases with a single hard drive but for models designed or marketed
for use as a server we also test with three additional drives. The acoustic
properties of the drives used are detailed above. Incidentally, the Seagate,
Samsung, and WD SE16 drives are the models used for our single drive configuration
mini-ITX, microATX, and ATX case systems respectively.
Baseline Noise
The DS380 ships with a trio of Globefan 120 mm 1200 RPM 3-pin fans with a distinct dimple-bladed design inspired by golf balls. It’s an older model included in some older SilverStone cases like the Fortress FT02 and Grandia GD05.
Stock Fan Measurements | ||
Voltage | Avg. Speed | SPL @1m |
12V | 1200 RPM | 34 dBA |
9V | 950 RPM | 27 dBA |
7V | 770 RPM | 21~22 dBA |
5V | 540 RPM | 15~16 dBA |
Measuring mic positioned 1m at diagonal angle left/front of case. |
The three stock fans combined to produce a loud 34 dBA@1m at full speed but they undervolted well, quieting down to 15~16 dBA@1m at 5V. The fans had a starting voltage in the 4.0V to 4.5V range so 5V is a good lower limit to ensure they spin up properly.
Also keep in mind that the lower noise levels are only possible with all three fans connected if you have some kind of fan control, which the DS380 doesn’t offer. As most mini-ITX motherboards are limited to just two fan headers, SilverStone includes a pair of extra headers on the drive cage but they are not controllable.
The Globefan’s acoustic character is generally smooth but there is an underlying clickiness that is especially prominent at lower speeds. At higher speeds, the increased turbulence hides this defect well but it’s still clearly audible if you get up close to it.

Equipped with only a single hard drive, our test system proved to be little challenge for the DS380. The CPU and PCH chips were fairly comfortable on load, even with the fans set to just 5V. The power supply fan didn’t even spin up throughout testing, not contributing at all to the modest overall noise level of 21~22 dBA@1m. Hard drive vibration was a complete non issue in this configuration, as we could feel only very faint tremors at the top of the chassis. The only thing that stood out was the hard drive temperature — 37°C might be considered a bit high for a lone drive with direct cooling. Increasing the fan voltage to 7V resulted in moderate reductions in CPU and PCH temperature, and increased the SPL to 24 dBA@1m.
TEST RESULTS: Four Hard Drives
The difference between the one drive and four drive configuration was instantly noticeable. The noise level jumped by 3 dB and the acoustic profile was dominated by a strong resonance that waxed and waned every ~1.7 seconds. Tonal peaks at 90 and 120 Hz corresponding to the drives’ 5400 and 7200 RPM rotational speeds, pulsed up and down.
The drive cage itself is well-constructed but the way it links up with the rest of the chassis does nothing to mitigate the side-to-side reverberations generated by mechanical hard disks. They are easily passed on to the rest of the case creating this annoying throbbing.

The addition of three drives also made it more difficult to keep the system cool. On load, with the fans at 5V, the CPU and PCH heated up by an additional 3°C and the original hard drive warmed up by twice that. The rest of the drives were only lukewarm and surprisingly, increasing the fan speed to nothing to help cool them down. The extra airflow helped the other components but the drives were essentially unaffected.
As the intake fans are located on the left side, the system was a touch noisier when measured from that side (as we typically we do). When we positioned the mic on the closed-off right side of the enclosure, the noise measured was 1 dB lower across the board.

Compared to other mini-ITX cases housing our four drive server configuration in an idle state, the DS380 was a bit noisier (when measured from the left) and exhibited higher drive temperatures than the rest of the field.
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 5~10 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
For a SilverStone case, the DS380 is surprisingly utilitarian. It has some of the flourishes SilverStone is known for like the brush aluminum door and the easily accessible external dust filters, but on the inside, things are considerably more Spartan. The underlying idea was to create a case with an eight bay hot-swap drive cage in as small of a space as possible, but in doing so, they made some design compromises and neglected other areas.
The complete lack of cable management is notable for any case at the US$150 price-point, and this is magnified by how tight everything fits inside, especially with a bigger CPU cooler. The choice to limit power supplies to SFX models saves quite a bit of space, but keep in mind most SFX models are not modular, and you really only need four power connectors to power everything, leaving a few cables leftover and no place to tie them down. To make assembly easier, the drive cage is removable, but the primitive scheme they came up with to mount it makes it heavily prone to drive vibration. The system we assembled resonated quite strongly with just four drives and it could only get worse with additional storage. While it’s hard to make any eight drive system quiet, it’s practically impossible without any fan control. This absence is notable as SilverStone has included some method of reducing fan speed in most of their previous cases.
The intake fans themselves aren’t very effective at keeping the hard drives cool either. It’s probably a combination of the fans’ side positioning, the restrictive drive cage, and all the cabling blocking airflow. The one thing it has going for it in the cooling department is the CPU cooler height limit, which is much higher than specified if you make the right hardware choices (a thin tower heatsink and a motherboard with the CPU socket far away from the expansion slot). SilverStone also included a long video card option if you’re willing to sacrifice a drive bay, but we could have lived without this. We can’t imagine there’s a large subset of people using their 6~8 drive servers for games, and in any event the case’s cooling isn’t really conducive to that sort of thing.
Despite all its problems, merely existing is enough to make the DS380 a compelling case for DIYers looking for massive amounts of removable storage within reasonably small dimensions. It is somewhat louder and rougher around the edges compared to most SilverStone cases, but the primary functionality is sound and the DS380 the first to fill this small niche.
