- Specifications

2. Package, device

The Shuttle DS67U is shipped inside a cardboard box with a familiar design. The box is rated as being able to work 24/7 provided that there is free circulation of air amongst the PC, ventilation holes must stay clear and if a hard disk is installed, this must also be approved for permanent operation by its manufacturer. The device consumes 10~12 W (depends on peripherals) while idle and 17 W / 25.5 W (CPU / CPU+graphics) under full load.

Looking at the side, you see a sticker with the product hardware specifications, but also a small warning regarding the SODIMM memory modules we need to use (1.35V DDR3L):

Opening the package, the main device is protected and placed next to a smaller cardboard box, which includes the rest of the accessories:

  1. Multi-language user guide
  2. Two metal feet with four screws M3 x 7
  3. VESA mount for 75/100mm standard (two metal brackets)
  4. Four thumbscrews M3 x 5 mm (screws together VESA mount and PC)
  5. Four screws M4 x 10 mm (to fix the VESA mount to the external surface)
  6. Rack (to mount a 2.5" storage in the bay) with two screws M3 x 4 mm
  7. Two antennas for WLAN and Bluetooth
  8. Driver DVD for Windows 7, 8.1 and 10 (64-bit)
  9. External power adapter with power cord

In order to get the box running you will need to install SO-DIMM DDR3 memory rated at 1.35V only and of course a 2.5" HDD/SSD drive. We would like to thank Crucial for providing us with an 16GB (2x8GB) CT2KIT102464BF160B memory kit (~80 Euros) and a Crucial BX200 960GB SSD (~303 Euros) for our tests. Of course users can install lower capacity SSDs if they wish, like an Crucial BX200 240GB SSD (~82 Euros) to get their system ready.

The product is compact in size (200 x 165 x 39.5 mm), making it easy to be installed behind a 24" LCD monitor and be completely hidden. It weighs less than 1.5kg, without any memory or SSD installed:

Both sides of the box have ventilation holes.

At the front panel of the barebone there are two USB3.0 and two USB2.0 ports, along with with power/HDD leds and the power button. In addition, the SD card reader (SD, SDHC, SDXC) will become useful for many users and of course the COM1/COM2 ports are essential for industrial applications.

The rear side includes a Display Port (DP) v1.20 and a full sized HDMI v1.4 port. Too bad the box doesn't come with an HDMI v2.0 that could support up to 4K 60p and HDR TVs... Anyway, you also get two additional USB2.0 ports, two Gigabit LANs, two WLan antenna connectors (supplied), the DC-In port and a MIC-in and headphone jack.

The supplied 75/100mm VESA mount is ready to go and allows us to mount the computer to a wall or on the back of a monitor

3. Installation, BIOS

The removal of the back covers reveals the motherboard interfaces. All you need to do is unscrew the two screws of the bottom cover and slide the cover forward and upwards.


First you need to have 1.35V DDR3L memory modules. Be careful with that, since the box will not power on otherwise. Locate the SO-DIMM slot on the main board, align the notch of the memory module with the one of the memory slot, gently insert the module into the slot in a 45-degree angle and finally carefully push down the memory module until it snaps into the locking mechanism.

In order to get the HDD/SSD installed, first you have to unscrew the rack from chassis, place the HDD or SSD in the rack and secure it using the e two screws at the side. Lay the HDD or SSD into its drive bay and push it gently to the right until it clicks into place and refasten screws. Below you can see both the Crucial SO-DIMM and the SSD components installed:

Below you see a picture of the bare motherboard. You can have both a 2.5" HDD/SSD and an M.2 2242M SSD installed at the same time, in order to get more storage capacity:

The Intel Celeron processor is visible at the back side of the main board:

Shuttle suggests that the barebone should be usually operated in a vertical position, using the supplied aluminum stands (DisplayPort output facing up). Another option is to mount it behind an appropriate monitor using the supplied VESA mount kit. From a thermal point of view, horizontal operation is permitted, although there are not any rubber pads to keep the barebone cool. At that position, the maximum operating temperature is 35°C.

Finally, the included Wifi antennas can be moved as the following picture shows, either in a horizontal or a vertical position:

- Bios / Installing Windows

You are free to install almost any operating system. Shuttle offers drivers mainly for Windows 7/8/10 and of course you can also choose to install your favorite Linux distro (like Ubuntu). In our case, we chose the Windows 10 installation. After creating a Windows 10 USB, you have to enter the BIOS are (pressing del at boot screen) and set the USB as a boot device. The installation was completed within some minutes and most of the internal components were recognized without needing to install additional drivers.

The DS67U Shuttle is still sticking with an Aptio Setup Utility interface, so no flashy UEFI effects here. The system is based upon AMI BIOS and its rather easy to navigate. The menus are available on the top area of the screen. The Main area shows details about the currently installed BIOS version, the installed processor and the amount of installed memory. Here you can also adjust the system's date and time.

The Advanced area comes with the following sub-sections:



The system was updated to the latest v1.02 BIOS. You have to use a DOS USB flash drive in order to update it.

4. CPU benchmarks

The system we are testing includes the following components

The Intel Celeron 3855U is a dual-core 64-bit mobile microprocessor released by Intel in the third quarter of 2015. The 3855U was designed to replace the Broadwell-based Celeron. Manufactured using the 14nm process, the Skylake-based 3855U Celeron processor can be configured to run at down to 10 Watt TDP. This processor, just like its predecessor lack support for any of Intel's advanced technologies such as hyper-threading, trusted execution, transactional synchronization extensions (TSX), and turbo-boost:

The DS67U series can be ordered with various processors installed, ranging from the Celeron 3855U to an i7-6500U. Of course, getting a faster CPU based DS67 system will cost you more. The DS67U3 packs a Core i3-6100U processor and costs almost 413 Euros vs 286 Euros for the DS67U... That's a 187 Euros difference for almost double the performance:

The installed Crucial Memory runs at 1600MHz at CL11:

The CPU-Z software has an included benchmark that gives you a rough idea of what we should expect from the Intel Celeron 3855U:

Below you see more benchmark results of the Celeron 3855U @1.60 GHz, compared with other desktop CPUs:

The Passmark 8 software provides more information related to the horsepower of the Intel Celeron 3855U CPU:

The AIDA64 Extreme Memory tests unveiled a great memory performance:

The CineBench benchmarks also offer many interesting results, so go ahead and click at links below to see more comparisons:

CineBench Rendering x CPU
OpenGL Standard
15.51 FPS

The PCMark 7 gave an overall score of 4230:

PCMark 8 offers more results for computing tasks similar to those you are performing in your home, creative and working computing environments:

The Shuttle system got a 881 score at the Intel Extreme Tuning Utility.

5. GPU benchmarks

The Shuttle DS67U is based on the Intel Celeron 3855U processor, which includes the Intel HD 510 Graphics. GPU-Z provides some details:

The Intel HD Graphics 510 supports up to 1.7GB of dynamic, shared memory, which are actually memory resources "removed" from the system's main memory. The PassMark 8 software gives us an estimation of its graphics strengths. Don't expect any serious performance here -- it looks like the HD 510 can reach the GPU power of an Nvidia GT630 and is also faster than Intel HD 4000.

The FutureMark 3D benchmarks returned the following results, which look typical for this category of GPUs.

3D Mark 05
3D Mark 06
3D Mark Vantage
3D Mark 11
3D Mark Sky Diver

To make things clearer, you can expect an acceptable graphics performance with DX9 games running at medium quality settings and at a resolution not higher than 1280x720p:

6. Audio and Video tests

It would be unfair not to treat the Shuttle DS67U as a media player system. The box has two digital audio/video ports and supports two independent screens: 1) DisplayPort 1.2 supports 4096x2304 @ 60Hz and 2) HDMI 1.4 supports 4096x2304 @ 24Hz. Both outputs support Ultra HD / 4K resolution, Quick Sync Video and Clear Video HD technology.

For our Audio/Video tests we used the following setup:

TV: Panasonic 55CMX710E (4K +3D capable) with the latest firmware installed
A/V Receiver: Yamaha RX-V775 (7.2 capable)
with the latest firmware installed
Wifi Router: TP-Link VR200 (802ac,b,g,n) with the latest firmware installed

We used several audio/video files from KODI Wiki. We also used the latest K Lite Codec pack and the Kodi platform.

According to its specs, the Intel HD 510 supports full H264, H265 8/10 bit, VP8/9, VC-1, AVC hardware decoding and HD video plus multi-channel digital audio via a single cable. With the Shuttle DS67U connected to our A/V receiver through an HDMI cable, we are ready to run some tests.

Note that in order to get automatically proper display scaling, we had to set the resolution to 3840x2160x23p. The 4096x2160x23p produced wrong scaling and we had to drop the horizontal scale to 50% under the Intel display properties.

Under Windows 10, it looks like the only 3D capable resolution was the 1920x1080p. The device locked at 23.975 fps with any video playback software we tried.

In order to get HD Audio you need to make some settings first. At the Media Player Classic (part of the K Lite Codec) you need to set the external filters . In KODI, you'll have to set audio to WASAPI HDMI of the TV Display and at 7.1. At the same time, you'll have to enable all the corresponding modes of your A/V Receiver.

As you see above, the audio compatibility was perfect. With KODI we easily got HD-Audio pass through along with a perfect audio playback; with the Media Player Classic you only get PCM 2.0 with AAC/LPCM formats. So using KODI is highly recommended.

Video Bitrate Tests

For this test we used a test file available at this page. The player was tested with up to 400Mbps files using all the possible sources:

Maximum Perfect Playable File with Media Player Classic
USB LAN (1GBit) Wifi (802ac)
Jellyfish H264 files 250 Mbps 250 Mbps 120 Mbps
Jellyfish H265 files 110 Mbps 110 Mbps 90 Mbps

Based on the Intel HD 510 graphics engine, the Shuttle DS67U maxed up to 250Mbit H.264 files. What you will not get is support for 10bit H265 files, as we experienced an unstable video playback. So you'd better connect the device through LAN (1Gbit) or even Wifi, as long as your system supports the 802.11ac mode (5GHz). Generally, the results here are good.

The player also showed a great compatibility with the H265 videos we tried, and had no problems with all the 8bit files. However, due to a limitation of the Intel HD 510 engine, the DS67U cannot playback 10bit or 4K VP9 videos properly.

We also tried to get 3D playback using both the Media player classic and KODI, but we encountered many problems...

7. Final words

The DS67U XPC Slim barebone from Shuttle is built on the same chassis we have previously seen with the DS57U series and besides the updated platform, Shuttle has added the M.2 slot instead of mSATA or the external Wi-Fi antennas for extended storage instead of the internal ones.

Generally, the device packs lot of power for its compact size. The fanless box is rated for 24/7 operation and consumes 15 Watt of power, making it ideal for users who need performance and efficiency.

We tested the basic version of the DS67U series, which comes with Intel Celeron 3855U dual-core processor installed. To get the device running, you'll need to install a hard disk drive (SSD or M2 slot), DDR3L low voltage memory (up to 32GB) and of course an operating system.

The barebone offers a rich set of I/O ports; it has many USB 2.0/3.0 ports, two Gigabit Ethernet, dual Serial com ports, SD card slot and 802.11ac / Bluetooth. Shuttle has done a great job in the design and build quality of the device, and has bundled with it VESA mounts in order to install it behind your office monitor.

The box doesn't come with any OS pre-installed, so you you can go either with Windows, Linux or perhaps even MAC OSX. In our case we used the latest Windows 10 version. The installation process went smoothly and lasted just a few minutes, provided that we used n SSD.

The Intel Celeron 3855U provides a good performance for office tasks and perhaps the Intel HD 510 graphics engine can play DX9 games at low resolutions and with the quality details set to medium. In our opinion the provided power is enough for everyday use, as long as you don't mess with harder tasks (demanding gaming, 3D, Autocad, etc..). There are also other versions to be taken into account which do feature the Core i3-6100U, Core i5-6200U or the Core i7-6500U processors for even higher performance needs. However, such a stronger configuration result to a double cost for you.

We also liked the fact that the Shuttle DS67U works with KODI 16.1 very well and that it is able to playback HD Audio (7.1) and up to 4K digital content. However, hardware limitations of the Intel HD 510 make playback of 10bit video files tough.

We had a lot of fun playing around with the Shuttle DS67U. With a wireless mouse/keyboard, it can replace your everyday PC system. It is economical enough consuming just 15 Watt and costs around 226 Euros.
