It uses the Realtek 1186DD chipset. It's about $78 + FS on eBay right now. Wireless version is about $92 shipped.
It plays 3D ISO files, mkv, mp4, avi, ts, and other media formats. It can also do 3D mkv's like SBS and OU. I bought this because I didn't want to shell out too much for a dedicated HTPC or pay a premium for the Dune/Popcorn boxes.
Connectivity is ethernet, USB 3.0/2.0, NFS, UPNP, SMB, eSATA. I did have stuttering issues with streaming certain 3D blu ray iso files (Avatar, Dredd) via NFS (most likely a NFS server issue on my end), so I am using a USB 3.0 external drive for 3D ISO content. All other content stream fine via NFS.
