Nice, you must be into deep learning with such a setup, any particular reason the deep deep learning models and GPU run in your server rather than in a powerful desktop system? Maybe you're actively offering AI services to the outside world?
It is a powerful desktop system as in it's housed in a desktop case and uses a "non-server" CPU.
Which like any computer can be a server. Being a server is more of a role than a form factor even if there are form factors specifically aimed at servers (rack mounted).
