What do you want to actually achieve with it? In the past I always had the urge to tinker and set up home servers to self-host pretty much everything, but at some point it just gets old and I realised I was just wasting time instead of spending it on either billable work or just take time off to see friends/family. Since then I've given up on all of that. So unless you have a specific goal in mind that can't be achieved with an off-the-shelf device or affordable SaaS solution, don't bother, and sell/give away the NUC if you have no use for it.
