Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
Why not just build the HTPC with a microATX? Most of which are WAY WAY cheaper and WAY WAY BETTER!
Actually, it will handle blu ray just fine. I have one of these already and it does BD without any skipping, stuttering or anything else. Flawless playback with great color saturation and crystal clear video. The audio on this is awesome, way better than traditional PC audio.
This board is great for HTPC. Great I/O connectivity, great video, great audio, that is why you would use this.
Sure there are other basic PC platforms out there, but none that are addressing the market needs like this one.
