I just built a new, custom media center PC, so I don't need this anymore. It includes the Mede8er (which plays almost every format of media you can think of including BluRay ISOs) and a preinstalled 750GB WD Green drive. The Mede8er sells for ~$200 on it's own, an for about $300 with a drive in it. It's in great shape and includes the remote, so I'm thinking $200 for it. If you have any questions, I'd be happy to answer them for you!
PS: To give you an idea of what this does: I would rip all of my BluRays as ISO files and store them on the Mede8er. I could then play them on my TV in 1080p with full digital surround sound.
