Good prebuilt HTPC for DVD/BluRay ISO playback?
 

Any ideas?

I use a WD TV Live for my DVD ISO collection.

But it needs direct USB connection, as wireless is too weak for streaming ISO. The bandwidth is not there. I'd need wired gigabit for that -- especially for Blu-ray ISO -- and the WD TV Live doesn't have that.

I started playing with XBMC and am now a big fan. I believe that while it can't play full Blu-Ray menus, it can still play the video files inside with the help of AnyDVD HD, which I would recommend anyone trying to back discs up.
