Marvellous stuff, glad to hear that progres is being made
Regarding the 2.5Gbit ports on the MS-01. I haven't had any stability issues with them however they do seem to be a bit painful to work with as in Server 2022 the drivers for them have to be bodged to work on one of the units since Intel doesn't have any official drivers to use for "Server" grade operating systems and the other for love nor money can I get the AMT function to work for OOB management. It seems that the better option is to go the route you have and to use PCI-e add in cards for anything that needs a truly stable network connection on the units
26-30w is great and is the real push with these sort of units, don't get me wrong they are by no means enterprise grade but the amount of power you get in these considering the form factor and power consumption is amazing
I've added a third unit into my setup to use as a backup hypervisor and to host my Veeam VM and like my other two hosts it's loaded with an additional X710-DA2 card for 4x 10Gbit connectivity and it works just as good as the first two.
One discovery I did make is that it appears to have made it back to Minisforum HQ that the thermal paste being shipped with the units was poor as out of the box it had a noticeable thermal improvement so it appears that is consistently fixed going forward. I've still re-pasted the unit as whilst it was improved with the X710-DA2, 2x 32GB DIMMs and 2x 1TB NVMe SSDs it was still pushing 55c when under small loads (Admittedly with regular spikes to 55c but between 30 and 40) however after the MX4 was applied it now tops at 47 as a peak.
It's becoming a bit of an addictive habbit getting a hold of them
