Hello again bg. That looks like an excellent HTPC build. You could go smaller on the PSU, and you may want to go for a blu-ray drive that comes with playback software, but I really have nothing else to offer. Looks like you've taken the forum advice to heart.
Actually, I think this is the blu-ray drive you're looking for. The one Stickmansam linked to only shows it includes burning software (Power2Go 6). This Lite-On drive includes Cyberlink's BD Solution which includes play-back software:
It's a good quality power supply, but I don't see why you'd spend $46 on that PSU when the $27 Corsair Stickmansam linked to is of equal quality and is more powerful. I get that you don't need that much power, but it's not going to hurt anything by having it.
