One caveat I was (more or less actively) ignoring is that when the server shuts down, it stops powering the mikrotik and so I cannot access the BMC to restart it etc… On a related note, I am afraid that a remote session to the BMC tunnelled through the mikrotik will not survive a reboot of the machine, which might prevent me from getting to the BIOS screen, should I have to reconfigure something remotely.

Thanks 😀 But you hardly get to control what that CPU on your graphics card does the same way as you get control over the Linux machine that is this router, do you?

(Oh, and actually, my first and last discrete GPU was an ati 9600 xt or something from over twenty years ago, so, I guess that statement about my inexperience with it is still standing 😉 Until somebody comes along to tell me that the same could be said about raid controllers etc…)
