Put one of these together with a C2D E7200, 640 GB WD, DH-4O1S BDROM, and an Antec Minuet350. It is plugged into a Sony HTIB and then to a Visio VO47 via HDMI. (I am not an audiophile.)
Based upon all of the comments about NB heat, I attached a 92MM fan to the case cover grille right above the NB, blowing down, and connected it to the CH FAN connector. I have it set as "Optimized" in the BIOS and it usually runs around 900 RPM.
Installed Vista Home Prem, the basic chipset drivers, FFDshow plus Hali, and PDVD8. I was prepared to spend a day tweaking it before I took it into the living room but it just wasn't needed. Compared to my last Gigabyte/ATI/AMD build, this was simple.
It plays anything I throw at it. BD looks as good as the other system and SD DVD and downloaded shows are also on a par with the ATI and that is with no changes to FFDshow.
The best thing of all is that resume from S3 works every time. I used to have to reboot the ATI to get the picture to come back so I added an iMON to shut the computer down and boot it back up.
I am very pleased with the setup and have actually been able to show my wife how to run it with the Harmony One and an MS MCE IR adapter.
