Quick question about the "Steam Machine" build: Is this intended to run SteamOS, or just intended as an HTPC that runs Steam? If it's the former, is a Radeon card really the best option for a SteamOS machine? Pardon me if my ignorance is showing, but last time I dabbled in SteamOS, the official Nvidia drivers were far more stable in Linux that either the FGLRX or radeon drivers. If it is the latter, then I agree that it's a good performance platform that could use a bit more RAM.
