First prototype of Bitfury S-HASH board is hashing:
Features:

16 Bitfury ASIC capacity
Adjustable (through 0805 SMT resistor) voltage regulator between 0.7 and 0.9V
Core voltage regulator has 50A capacity, so chips can be overclocked.
On-board ARM Cortex M3 processor with standard RJ-45 100 Mbps Ethernet port.
Built-in mining software can operate stand-alone. No PC or Raspberry PI needed, just an internet connection.
TCP/IP stack with DHCP and DNS support. Just fill in pool server name, port number, username and password.
Support for Stratum and backup mining pools.
Built-in small webserver for chip status/speed reports.
PCB temperature sensor, could be used for automatic shutdown when temperature gets too high.

If you don't have the budget for a large number of chips, overclocking is the best option, as it will get you 40GH/sec out of a card (probably more with better cooling), instead of 25GH for a standard H-CARD for the same 16 chips. At 40GH/sec, the card uses about 35 Watts, running off a standard 12V DC supply.

40GH/s with only PC fans blowing onto the chips and no heat sink! Wow!

To avoid confusion, please note this image and the specs do NOT refer to the same Bitfury 55nm ASIC H-Board being sold by megabigpower. This is a modified prototype board, with very different features from the H-Boards we've been discussing so far on this thread. In particular, this kit is a self-contained miner, not requiring a master board to plug into, and has different components which allow the overclocking (which will not be possible with the current H-Board out of the box AFAIK).
