Mini PC vs poweredge r730xd server. What are your thoughts?

I have seen a lot of people on reddit claiming that getting a mini pc is better than an enterprise server. But when looking at the price of an N100 vs the price of a used poweredge r730xd even assuming international shipping of over $500 if you buy from eBay and don't live in the US. Many of them build clusters that would cost more than one enterprise server, it seems like a hassle.
