Four SATA cables are bundled with the ECS HDC-I, along with the usual I/O bracket, driver CD and manual.
A mini-PCIe WiFi b/g/n module is included together with an antenna and rear brackets (both full- and half-height. It is not preinstalled but the necessary screws are included. We would prefer to see the antenna mounted on the rear I/O panel as some small form factor casings may not have a spare rear bracket.
The ECS website lists the WiFi module as an optional item, but we have asked ECS about this and they have stated that it is part of the retail package.
Unlike some pictures shown in previews, the final version of the ECS HDC-I uses a 40mm fan to cool both the E-350 and the AMD Hudson M1 chipset. This doesn't come as a surprise since Asus had to use a much larger heatsink to achieve passive cooling, even considering the low 18W TDP of Brazos. The fan runs pretty silently though.
The layout of the board is quite standard and we could not identify any problems. Remember that Brazos only has a single 64-bit memory channel, so using two sticks of DDR3 will not grant any performance advantages.
Four SATA 6 Gbps and one eSATA port are provided on the ECS HDC-I. The chipset actually supports up to six ports, but this is really more than enough given the intended usage of such a low-power system.
ECS has opted to include VGA for convenience, in addition to DVI and HDMI. There is also an integrated Bluetooth module, which uses the Asmedia controller we previously saw on the Asus E35M1-I Deluxe.
Two USB 3.0 and six USB 2.0 ports can be found as well as 8-channel audio powered by a VIA codec.
