These mounts adapt the stock N64 board mounts to the Intel NUC motherboard and an M.2 to SATA adapter, as a full size 2.5" SSD was too large to fit in the case. A rear cover is also inserted behind the storage adapter to cover where the original AV port used to be accessed from.

A custom rear I/O shield matches the profile of where the stock AC adapter would normally plug into.  Additional holes were added to mount the wireless antennas to, and a vent was included to allow the blower-style fan under the motherboard to exhaust out of the case.
