MissingRemote published a review on the Intel Next Unit of Computing (NUC) D54250WYKH - "H" is for 2.5" HDD Mount A quote from the article:

When Intel brought out their Haswell Next Unit of Computing (NUC), inclusion of features like SATA made it clear that they had bigger things in store for the little system. They were honest that some of this promise will require 3rd party case OEMs to fully realize, but Intel quickly announced that they would be creating their own chassis with 2.5” drive support a bit later. Providing this feature is interesting to two groups of users: those who have, or want to leverage a 2.5” SSD instead of mSATA or anyone who wants local, rotating, storage in the NUC. As it happens, now is the time, and when I sat down with Intel at CES to talk NUC they had one of the new 116.6mm x 112mm x 51.5mm enclosures for me to take back and run through the paces.
