Looking for some info about Archer VR1210v

Hi, I'm new here, but not new to alter-firmware on routers.
I'm looking for some information (CPU, RAM, speed) about a rather unusual hardware Archer VR1210v which I recently purchased due to USB 3.0 and I'm going to make something like a NAS out of it.
From what I can see it is not supported by OpenWRT or any other, probably due to the fact that it is quite rare hardware.
I suspect that the firmware from version VR900v will not be compatible with VR1210v.
Are there any chances of getting interested in this router and creating a Firmware for it? This hardware has probably a pretty good processor and some ram and USB 3.0, which makes it a nice base to play with.
Thanks for the info....
