Came across this when I was browsing for a Mini-ITX board for the in-laws MCE, and it seemed too interesting to pass by - only one in stock
Information on this board seems pretty scarce, Asus's website doesn't even have a product page for the HDMI-equipped variant yet. Only difference seems to be the HDMI port though, so this link should provide some details: http://www.asus.com/Motherboards/Intel_CPU_on_Board/C8HM70I/
Intel HM70 chipset
Intel Celeron 847 ULV CPU, dual-core
Dual SODIMM slots, max 16GB RAM, DDR3-1066
PCI-e x16 slot
1 SATA 3Gb/s port, 1 SATA 6Gb/s port
2 x USB 3.0 ports on back panel
The board was not too expensive, paid around 80 euros for it. Currently I am just using it for testing / playing around, but it will probably end up on a family members desktop at some point. Test system currently consists of:
Asus C8HM70-I/HDMI motherboard
1 x 4GB Kingston SODIMM DDR3-1066 module
OCZ Vertex2 60GB SSD
bequiet PurePower L7 350W PSU
The CPU is cooled by a heatsink attached with pushpins, and a 40mm fan on top. The stock fan runs @ 4300rpm (apx) and sounds quite 'buzzy'. The motherboard has a 3-pin header for the CPU fan (monitoring only, no "smart" BIOS controls for fan voltage), and a 4-pin PWM header for a system or case fan - this does support Asus' 'Q-Fan' control system though.
With the stock fan, the CPU temperature reading just sitting in the BIOS is apx. 30C. This is on an open testbench (Lian Li T60), 22C ambient. I replaced the stock CPU fan with a Scythe Mini Kaze 40mm, 10mm height fan - at 12V this does apx. 3500rpm. This is a lot quieter, and does not exhibit the same buzz as the stock fan. I have since put a 9V resistor on the Scythe, which helps even more.
Will update this thread with some more details when I have time to test some more ... Am planning to test Netflix HD streaming in Windows 8, Blu-Ray playback with Arcsoft TMT5 and maybe a little stress testing of the CPU (Prime95 or similar). Will measure power draw as well.
