How much for itx x99 system?

I have a x99e itx system with xeon e5 2699v4 (22 core). I have a quadro t600 and 48gb of ram. I think it might be worth around 300 with all the things. It would make a good beginner server for someone. It comes complete with case, psu and ssd. I plan on selling local to me through fb market place. Anyways is 300 too much to ask for?

300 of which currency?

USD. Being sold in US.
