The retail end-user version of the H3.SODD ships with a power cable, special set of screw drivers and a cooling kit consisting of a tube of Arctic Silver Ceramique thermal interface material, 6 x 6 mm copper heatpipes, the two CPU heatsink (evaporator) sections that sandwich them, and mounting hardware for Intel LGA775/1155/1156 and AMD AM2/AM3 sockets. There is a nicely illustrated installation guide. In addition, we received a standard Windows Media Center remote control, which is sold separately by HDPLEX.

The heatpipe CPU cooling kit is very similar to the one in the H10 as are the other accessories. .

Undoing the four screws in the corners allows the top panel to come off. The power button at the left corner of the top panel really is a small button that falls off when the cover is removed. It works fine in normal use; a piece of adhesive tape is used to ensure it does not fall off when the cover is mounted back on.

The case was supplied with the following system installed:

  • Intel i3-2120 (dual core, 3.2 GHz)
  • Asus P8H67-I Deluxe mini-ITX motherboard
  • Samsung 2 GB DDR3-1333 SO-DIMM
  • G.SKILL Phoenix Pro FM-25S2S-60GBP2 SSD
  • 80W Fanless Open Frame Fanless Power Supply (Magic Power Technology MPI-706H)
  • Slim slot loading Bluray drive
  • Windows 7 Ultimate, 32-bit

With the OS and the Blueray drive pushing the price up by nearly $350, the sample system price is just under $1,000. The system is obviously very speedy, with only SSDs for storage. The boot time seemed as quick as any other system seen in our labs, and the windows menus zapped to and fro instantly.

Interestingly, a no-optical drive option is available in the H3 series, called H3.S, which eliminates the slot opening in the front panel for a $10 reduction in price. In other ways, it is the same product. This is the obvious option for those who have moved past optical media with online media services and resources.

Banks of fins from a substantial aluminum extrusion protrude from the sides to dissipate heat. They are 5.0 mm thick at the base and 3.1 mm at the tip.

Some of the cables could be a lot shorter, but they don't get in the way of any airflow.

The CPU heat is transferred to the left heatsink fins via six copper heatpipes. The open frame power supply, whose housing is part of its cooling, is bolted directly to the right side heatsinks. The securely mounted power supply is subjectively a big improvement over the external AC/DC power supply that was custom-fitted in the H10. There is no chance of any loosening of bolts or brackets here. It gives the H3 a considerably more polished feel than the H10, even though most of the other details are similar. Cables are bundled with velcro ties, and the two SSDs are hidden under the Bluray drive. Most of the internal space is well utilized, though it is not jam-packed.
