Everyone,
I am wanting to begin moving all of my movie purchases to Blu-ray from standard DVDs and need some expert advice on how to get started. I currently have a Media Server in my house which I use for mp3s, DVDs, and home movies. My rig is a couple of years old and it is running Windows XP Media Center 2005 with latest SP. Hardware specifics are in my signature. I have AnyDVD HD already installed.
Question is could I get by, initially, with adding an external BD drive (would like to read and write so I can use BD disks as file backups). If so, which drive model would you recommend? As being new to Blu-ray, I am concerned I do not know enough YET

as to any technical or performance limitations I might run into with my current rig.
So questions is, purchase BD drive and connect externally via USB2.0 and a HD enclosure, or purchase a new PC?
Thanks for any suggestions!!!
