I tried an Intlel NUC with openElec (XBMC/Kodi install on a tiny Linux based OS, only need 200MB to install and some additional space for the media databases, so a 30GB SSD is way big enough).
Intel NUC (mine is the i3 version) has two USB 3.0 sockets, HDMI and Display Port and 1GB Ethernet ( you can fit an optional wireless card). Also has IR remote reader. All in a box about 100mm square and 30mm high.
Anyway, As I said in an earlier post, I primarily use my media player for music (multichannel audio only and 5.1 Music concerts). I loved the Mede8er and M8 IPad remote app BUT I could not navigate through my music collection while playing a music video. I reported this to Mede8er and the app developer but they wouldn't fix it (Mede8er firmware).
XBMC (now Kodi) on the NUC with any of its IPad remote app's does allow me to navigate through my albums or music video tracks while watching or listening to something (the TV/projector is independent to the IPad app screen), in fact I found an app that allows me to make a 'play queue' (playlist) 'on the fly' that can have a mixture or video music or audio only tracks.
The app is called XBMC Music Remote Pro. Worth a try if you have XBMC/Kodi and you play music and/or music videos: http://www.xbmcmusicremote.com
