And let me add mine to the "key length collection": DHO1074 HW2, bought at the BF sales from Amazon Germany (Rigol Europe), Key length 148 byte, Cal certificate date Jan 13, 2023

That's the exact same calibration date as my DHO1074, by the way. Also bought via Amazon Germany (from Rigol Europe) during the BF sale -- but, as mentioned, with HW version 3 and a 388-byte key (provided in FRAM only).
I would love to understand Rigol's logistics... I did double-check the serial number on my calibration certificate, an reassuringly it actually is the same number as in my scope. ::)
As mentioned earlier, I am not quite ready to break the warranty sticker until my "right to return, no questions asked" expires at the end of January. I will definitely look inside then and compare with your photos of the V2 hardware with its multiple piggyback boards.
TurboTom:
I guess the multiple replacements for the voltage regulators in the HW2 version aren't a big deal. But both the Network PHY (Motorcomm vs. Microchip) as well as the USB hub (TI vs. Microchip) are "piggybacked" in HW2 units which probably requires alternative drivers. It's well possible that in HW3, only one of these chips has been changed or they used even a different type... I'm already quite curious what you will find in your DHO1074 when you go and take a look. :D

My DHO1074 is HW 2 and calibration at 2023/03/28.
Bought at BF from Batronix.
thm_w:
HW3 388 byte key.data was present

Maybe can tell from lsusb:
--- Code: ---rk3399_rigol:/ $ lsusb
Bus 001 Device 002: ID 0424:2734 (Microchip hub)
Bus 002 Device 002: ID 0424:5734 (Microchip hub)
Bus 001 Device 001: ID 1d6b:0002 (root hub 2.0)
Bus 002 Device 001: ID 1d6b:0003 (root hub 3.0)
Bus 001 Device 003: ID 0424:274e (Microchip ethernet?)

Some interesting stuff here but I think only the pwm_fan can be controlled easily
