I’ve had issues with WD Green Drives when dealing with several streams. But my drives are a couple years older so perhaps the newer ones with the 64mb cache handle it better.
If you are going to be gaming on the HTPC you might check out AMD’s latest Fusion systems or expect to be adding a discrete card to your setup in the future. 1080P is a lot to ask for from integrated graphics when it comes to gaming. I have the 880G chipset and Dirt 2 ran well but I did have to dial the settings down a bit.
