ignoring the fact one would need a bit of a different setup (chassis, PSU) to run it, I casually looked and there's nothing below $25-50k euros for such a board decked out, depending on the config. TBH even that doesn't sound bad, but I wouldn't even know where to start how to run it.
This is from the USA site:

It's always a gamble buying used electric but per the description, fully decked out server with 256gb vram.
Though at 2U it is going to sound like a 747 taking off from your office.
So that’s where all the used V100s are going. I’ve been thinking about making a water cooled version of those because I don’t have a rack to put these servers on.
