That's a damn fine PC and don't let anyone tell you different, it will run reliably and do everything you need it to for as long as you need. I have some computers at work that are knocking on 13 years old and still chugg away reliably doing what they need to - in fact I am remote logged into one right now to keep an eye on the work network at home. Out of interest did it come with an OS pre installed or what will you run?
I installed Windows 10 Home Pro and work very good.
