I am now using Wake, Remote HD, Boxee and VLC iOS apps for controlling much of the PC since my Bluetooth has been a failure. I also moved the HTPC into the room behind my projector so their is no noise.
I tried connecting the PC to my 4x2 matrix so it could service my family room and home theatre but it simply refused to work.
I've ended up buying a WDTVLive Hub for my family room and the HTPC is used for the Home Theatre. If I don't use it much, I might just convert the HTPC into a desktop for the kids.
Time will tell.
