I am looking for a workstation MB with remote management and narrowed down my search to one of the new boards from ASRock Rack: B650D4U, B650D4U-2T/BCM, B650D4U-2L2T/BCM as these seem to be quite widely available in EU as of this week.

I am slightly confused with the naming: Does the lack of 'BCM' in the base version (B650D4U, this is the one with 2x 1Gbit and 2x m.2) indicate that it does not possess full IPMI/BCM capabilities?

BCM in this case indicates that the 10g nic is Broadcom as opposed to Intel. The board without the BCM does not have onboard 10g of either kind. All three have the same ast2600 bmc ipmi.

IMO the one without 10g is the better option since it has a second m.2 which can be turned into an additional x4 card slot via an adapter.

Thanks, that solves the issue. I guess I didn't read the text properly and misread BCM as BMC. The one with 2x m.2. definitely looks more flexible in this case.

Can you elaborate pls? My 10g does not have a second m2. Or did I miss it somewhere?

The two boards with 10GbE use 4 lanes from the B650 for the controller. The one board without 10GbE uses those 4 lanes for a second m.2 that's located at the back of the board.
