If I had that I would max the memory and put in a fast SSD and make it a bare metal Hypervisor. I'm sure you could throw anything at that NUC and it will keep on chugging away.
Yes it is overkill. No reason why you could not, and no reason why you would, as a free PC these days can run Hyperspin.
Read the forums and start asking questions and get it all working and have fun.
Congrats for snagging one of those units, and good luck with your build.
