Summary: I have this setup as part of a home theater PC and was really dissappointed that I could not keep it in sleep mode so I can record shows at any time (my software will wake it up).
Pros: Small form factor, noiseless, processor will run fine without the optional included fan. Only consumes about 45 - 65 watts while running.
Cons: 90% of the time this motherboard will not come out of sleep mode - either by keyboard command or by pressing the power button. In fact, once it is in sleep mode, if it won't come out of sleep mode, it won't power off either after pressing the power button for the requisite 6 seconds.
Cons: Thought it would be a money saver not to have to buy a separate graphics card. Was I ever wrong. Graphics performace is very poor. Got very low frame rates (2-4 FPS). Ended up installing separate GPU to get decent graphics performance.
Summary: I have three of these boards, and they work most of the time. Two were for HTPC setups. However if you stream netflix, the board can hang causing dropped frames. The third board I set up as a linux router. As previously noted, you have to install non-free firmware to get video.
Pros: Very low power and quiet. Decent performance when it works. HDMI output.
Cons: The AsusMedia PCI controller can momentarily hang windows or can cause a disable IRQ in linux. Search "ASM1083 PCIe-PCI bridge chipset" and look at widespread problems. Note that the Asusmedia PCI problem extends beyond just this board. Other PCI controllers can also have issues, just this one is...
Asus doesn't support Linux on this board; WOL doesn't work

Pros: Runs Debian Squeeze and Wheezy. Squeeze doesn't support the sensors through lm-sensors but Wheezy does. Wheezy requires firmware-linux and firmware-linux-nonfree in order for video to work. Easy to use bios, board will boot USB drives for super easy OS install.
Cons: With wake on lan enabled in bios, the board will reboot itself when issued a shutdown command. I contacted Asus and their official answer was "this board does not support Linux". Would've been nice to know before purchase. In order for board to shut down properly, wake on lan needs to be disabled...
