Not your scenario really but a HBA will allow you to use SATA and SAS drives. Gives a bit more flexibility on price, especially with 2nd hand SAS drives.

My drives are currently in a box supplied by wires hanging out of the PC (Server!) casing but it would look much neater with a 4 bay hot swap cage built for the purpose.

I just wish I could get the full 12 Gb/s out of the couple of SAS drives I use :o(

Oh yes!

You may be out of luck, but doesn’t that board have onboard VGA graphics which you can use?

OMV is a web page dashboard and there’s SSH. What is the usecase for a GPU I wondered?

Home network. The most fun was setting it up and finding out about ZFS, ymmv.

No multiusers, so I use a simple vpn to connect to my services from outside.

Apps use NAS ip address:Port and are easily viewed in a browser once installed.

I don’t need much else so I install services as they catch my interest. Tried Tailscale, now looking at NetBird which might be the way forward as they now have a reverse proxy for testing.

Anything else is a bit too complicated for me to maintain.
