Pros: I bought the i5 version because people mentioned the fan of i7 is much louder. It is still very fast for a HTPC. The size is small. The TDP is only 15W.

Cons: One of the main reasons I bought this is build my own NAS. I attached an external USB drive to it. However all 4 USB ports have disconnection issues. The external USB drive initially works fine but disappears after some time. The device manager shows exclamation mark on USB Massive Storage Device. I Googled it and it seems to be a common issue. I went to Power Options->Change advanced power settings->USB settings->USB selective suspend setting, and changed the setting to disabled. It does seems to solve the issue on the yellow USB port. But it still doesn't work for the other 3 ports. And since the yellow port is in the front, attaching an external USB drive to it is ugly.
