Can I ask why?
The latest UHD GPU support on this board is going to be unused in a ROCK build.
The latest Wireless-AC 9560 support on this board is going to be unused in a ROCK build.
In 99% of use case ROCK doesn’t need more than 8GB of RAM. Larger RAM configurations are only needed with very large libraries, circa greater than 500,000 tracks. There has been one report of a ROCK deployment running out of RAM and requiring 16GB.
Base clock speed for i7 CPU on this board is 1.8GHz, any time you come off that, with the Turbo boost to 4.8GHz the resultant heat output will throttle the processor unless there are huge amounts of active cooling. Hence the larger fan on the board, which will be noisy in every way.
Quad-Core CPU means 8 threads - ROCK initially only uses a thread per endpoint zone, (but can also support multiple zones in a single thread).
A single thread on a NUC5i3 with 8GB RAM running ROCK can support upsampling to DSD128 and downsampling of DSD256 with full Room EQ support at the same time.
A single thread can also support playback of 24/352.8 & 24/384 formats, plus all of the MQA formats and with simultaneous Room EQ as well.
A NUC5i3 with 8GB RAM running ROCK can also support 4 simultaneous zones running some level of DSP on each.
There are actual benchmarks for all of this in the List Your NUC Capabilities Here thread.
