Silverstone was clearly monitoring the forums with regards to the C2750D4I in order to come out with a case designed amound the concept. Our Silverstone contact also became aware that we had the motherboard in for testing and volunteered its DS380 for a quick overview. I installed the motherboard in to the case along with my rag-tag collection of storage drives (four 3TB Seagate Barracuda 7200.14, one 2TB Western Digital Green and one 1.5 TB Seagate Barracuda 7200.11) which were previously spread out across several systems.

The case has a top mounted power-supply section (we used the Silverstone 300W SFF PSU) and places the C2750D4I upside down, with space for an 11” dual slot GPU. For PSUs that have a top/bottom mounted fan, Silverstone’s design means that the airflow for it is out of the case.

The rear of the case has a single 120mm fan installed, and the side of the case (for blowing onto the drives) uses two 120mm fans – all three were included in our retail sample. The fans use a dimpled design to reduce fan noise.

The drive area uses a backplane, and SATA cables from the motherboard attach to this.  Users can install SAS drives using both SATA ports.

The case is designed for hot-swap systems, and as such the front eight bays allow the drives to be removed.

The front of the case has two USB ports, with the connector inside capable of being placed in a USB 3.0 header. This is where the case differs in being ideal for the C2750, as there are no USB 3.0 headers on board.  Had Silverstone offered this connector as a USB 3.0/USB 2.0 hybrid, this would have been more ideal.  There are two audio jacks as well should a user decide to place a different mini-ITX motherboard in the case and can take advantage of eight drive bays via an expansion card.

The front of the case is also lockable, although the key design is not a unique one. It does stop little ones pulling a drive out however.

The case is not a tool-less design, but a standard screwdriver is all I needed to put the system together. Because the C2750D4I has a small heatsink, cable management was easy enough, although the placement of the 24-pin ATX power connector meant that the cable had to go all the way across the motherboard.  At the top we also have the 4 bays for 2.5” drives:

Silverstone suggested the 300W PSU that we used for the build, but if a PCIe device was installed we would have had to have used a 24-pin extension cable.  Similarly, the SATA cables suggested had a small issue on the bottom SATA port:

Using my own ears (unfortunately I am not equipped to measure audio performance), the three fans installed, when active, were audible enough to disturb quiet scenes in a movie and you might not want it nearby overnight, but certainly silent compared to my normal PC or the busy road I live next to. Temperature readings from the CPU gave 40ºC at idle and 53ºC at load. Total power draw, at the wall with my drives installed using the 300W PSU on a 240V line was 52 W at idle.

Ganesh also has this motherboard in to test and will be examining the storage performance in due course.

    I'm with you Up, how did this get sidetrac'd into HTPC, I'm looking for an alternative to some of the stock Qnap and Synology geer for use in my home. Want NAS box with lots of tru put. Not clear on why Ian says no NAS. Whats up with configuring as a NAS? Any other suggestions

    Before you buy: the Areca PCIe X8 card won't fit in the ASUS AM1 board with only one PCIe X4 slot.

    Avoton supports intels visualization extensions with 64GB of RAM and 8 cores it could be a decent low powered KVM server sliced up in many different ways.

    I have to say I'm surprised they didn't go with minisas connectors instead of a fistful of satas. Supermicro have done the same thing and it simply doesn't make sense.
  • Samus - Friday, May 2, 2014 - link

    yeah they could have saved a ton of real estate using mini plugs. Even full sized servers like HP's ML310 series use mini plugs to keep the board clean. Even more important on an ITX board. This board has a lot of oversights, which ASRock will learn is unacceptable in the market they're targeting it at.
  • ericloewe - Friday, May 2, 2014 - link

    Bad idea in this case, since they're using SATA instead of SAS. Someone would inevitably try to use this with an SAS expander...
    But I agree with Supermicro having made an odd choice. Their LSI2308-equipped motherboards would be perfectly equipped with SAS connectors.

    if you're looking more for a media player you can plug into your TV, then one of the many other Baytrail-D motherboards would be suitable... there's a useful list and discussion of them here:

    i'm probably one of the core target prosumers for this, as for a few years now i've been running something similar at home...
    namely a sandybridge itx board, 35 Watt i3, ecc ram, supermicro low profile (lsi) sas controller, supermicro 24x (lsi) sas expander backplane, 400w passive psu, passive cpu cooler, 18 sata 2.5" hdds (5200rpm - WD scorpio blue / hitachi travelstar)

    and while this board fits my requirements wonderfully while being cheap there is just one dealbreaker... 12x sata? wtf? no-one sane will run so many hdds without a backplane. it's just unmanageable.
    the most simple backplane with 12 sata plugs + some power plugs & 12 correctly spaced hdd plugs woud do. and could be manufactured & sold very cheaply. but there is no such thing... (step up asrock :)
  • bernstein - Tuesday, April 29, 2014 - link

    to the point: give me such a backplane for below $100 and im sold. else thanks but no thanks.
  • ZeDestructor - Tuesday, April 29, 2014 - link

    With 18 drives, you might want to consider a BackBlaze pod with room for 45 drives, especially now that we have 32 and 40 disk controllers. That with some ZFS would be quite an excellent NAS IMO, and I am heading that way, slowly.
