Well not to spoil the fun, but I don't have any big problems with my i5 hasswell nuc anymore (D54250WYK)
Updated to latest bios v24.
Disabled Wake-on lan.
Disabled UEFI secure boot.
Put boot from USB first.
Installed Openelec snap nightly built "OpenELEC-Generic.x86_64-devel-20140209021212-r17682-g77f82ca" on my kingston usb 3.0 stick.
Which can be downloaden here :

On my internal msata plextor drive I've got an windows 8.1 enterprise installed.
Enabled SSH, used winscp to transfer my sources.xml.
Connected with LAN.
Run the autoscript to fix the IR (MCE remote). (autostart.sh)
-> ssh into terminal :
echo "#!/bin/sh" > /storage/.config/autostart.sh && chmod +x /storage/.config/autostart.sh
nano /storage/.config/autostart.sh
"
#!/bin/sh
# IR fix
modprobe -r nuvoton-cir
echo "auto" > /sys/bus/acpi/devices/NTN0530\:00/physical_node/resources
modprobe nuvoton-cir
"
In Openelec system settings turned on advanced and put sync to refresh rate.
For the 24hz content. Which is 95% of what I use it for. (1080p 24p)
**********
And here is the funny part :
After the bios update I had to boot my NUC once into windows, shut it down,
to be able to use my OLD mce remote to be able to power on the NUC with the remote.
Ofcourse I had to put my USB stick with openelec back in, which I pulled out to start
Windows from the msata.
**********
x264 movies seems to play flawless...
Doesn't reboot after 30 minutes, doesn't crash, can turn it off with my mce remote.
Use the remote to navigate and to power on the device.
It's quite silent when playing 1080p 24p content, even 3D half SBS.
I love my nuc
