Ok I picked up that drive you recommended. I got the white one since it was nearly ?10 cheaper. At firrst I couldn't play bu-rays, that PowerDVD app kept crashing. It worked fine playing DVDs though. Turns out it may have been a Windows update since it is the only thing that changed. When I rolled back it was ok again.
The drive itself is sleek and seems solid enough. It is also somewhat audible, particularly noticeable in quiter scenes, but it isn't noisy per se. You were also right about load times, but once it gets going, playback is smooth. The only "complaint" is the CyberLink OEM suite. It installs quite a lot of things I probably won't use and I had to disable quite a lot of the start up things.
