Hello, I was recently checking this MOBO.
I believe that MOBO for the Tower and SFF versions are the same. A cut down version (but not my much) is used in the HP Elite SFF (based on Q670 chipset).
One note, I don't think the HP FlexIO V2 10G ethernet is compatible with these motherboards. The connector is longer.
I think HP FlexIO V2 10G module only work in the HP Elite Mini and HP Z2 Mini.
