KitGuru tried the ASRock M8 Z97 Mini-ITX SFF System
A quote from the article:
We first saw the ASRock M8 Z87 small form factor barebones in the second half of 2013 when it was reviewed by my colleague Luke Hill. This latest Z97 version is a relatively minor refresh with an update to Intel's latest Haswell compatible Z97 chipset. The SFX power supply has been upgraded from 450W to 600W and that appears to be the extent of the changes.ASRock M8 Z97 Mini-ITX SFF System Review @ KitGuru
