Unraid J4105 Upgrade

I have been running an Unraid server with a J4105 motherboard in a Node 304 for 4+ years. Works great.

I am tapped out on SATA ports and would like to have the capability for 6 SATA ports plus 1 (SATA or NVME) for a cache drive.

A beefier processor would be nice but is not essential. I do a lot of Emby transcoding and Quiksync is a must for it. A low power consumption build is preferred.

Any ideas on a motherboard? If I could reuse my RAM that would save some money but is not essential if the performance is worth it.
