pcgirl you aren't providing detailed information about what kind of files you want to stream.
If it's compressed H264 stuff, it should work well over wi-fi and honestly, unless you want to use really heavy skins the NUC is potentially overkill (but certainly a really nice solution).
If you are wanting to stream full BD rips, wifi won't cut it.... you will want to do a power line (over AC) or hard wired ethernet connection to get reliable streaming of full bit-rate BD movies that you've ripped to MKV or other container.
I have just got the newer i3 Haswell NUC with integrated IR running in my setup and am quite impressed with it. It is 1/10 the size of the "mini" PC it replaced, it is almost totally quiet, the IR works superbly and it can handle pretty much anything you throw at it as far as performance of playback of large files go. I do use it on wired gigabit ethernet connection.
There is one headache area with Intel solution and that is around setup of black levels and color gamut for some AVRs and TVs but frankly most people aren't picky enough to notice the problems and have to work on getting it fully functional.

NUC DCCP847DYE
They work perfect for everything I have thrown at them (i.e Live TV, Movies, YouTube, etc...)
The only downside is they don't have built in IR
Note: If you should get this one, VC1 decoding is not automatically 'on' in the XBMC settings for OpenELEC. I rebuilt the first one I had three times before setting the Settings to 'Expert' and finding the problem...
The reason that VC1 is currently not automatically turned "on" for hardware decoding is that there are bugs with the current FFMPEG used in XBMC and trying to play back VC1 using hardware decoding, so software decoding is preferred and that's why it's set up that way.
This is supposed to be fixed in the next FFMPEG version which I think OE currently has in beta.
