The current Haswell Celeron 2955U (I was using a Chromebox) will decode and output 2160/24-30p 4K H264 stuff over HDMI. This was connected to a Sony 4K UHD set. I only tested a few clips but it was VAAPI decoding and CPUs were both sitting at quite low figures. I haven't tested anything other than HSBS 3D.

Thank you. Although FSBS or above might be a difference if the video decoder in the Intel IGP it can't handle that resolution well enough.
The new NUCs do look promising but I was more looking into a cheap upgrade of my current system. I would only need the mentioned Celeron G1840 CPU and one simple 1150 Mini ITX Board which is roughly 80€

I didn't know everything in XBMC could run that fast... the speed improvements coming from an AMD E-350 compared to the Intel Haswel Celeron G1840 are enormous. Full-SBS and 2160p Files I tested do run cooled passively and with <10% CPU usage. Awesome! And the video looks better somehow ... it's probably my imagination but I was thinking it repeatedly yesterday.
The only down-side: Every hour or so the video crashes and XBMC (current OpenElec frezes) ... but the temperatures at still around 35°C. Does anyone know what it might be? I did set up all C-Stage related settings (C6/C7) quiet aggressively towards energy-savings on my mainboard (ASRock B85M-ITX v2.1) and read this might cause some problems.

In SandyBridge/IvyBridge full framepacked 3D HD required at least an i3. I don't know if Haswell has changed that. Usually the way to know is to look in Intel ARK and see if the CPU says "Intel® InTru™ 3D Technology" under the graphics specification. I don't see that for the G1840 but it's there for the i3-4130 so I suspect it's the same.
