Lenovo ts140 Server Gaming PC

Is it possible to build a gaming PC/upgrade hardware with a Lenovo ts140 server to make a decent gaming PC. **Please don't butcher me alive for this question, I don't know a whole lot about PC hardware, specs, lingo etc. **
I just really want to get into PC gaming, but don't have $500+ to throw down on a prebuilt system (I play BF4, PUBG, Rocket League). But.. the company I work for uses lots of Lenovo servers and I'm sure I could get a heck of an employee discount on a used tower.Or would it even be worth it?

Thanks,

From what I could glean from the websites for this PC, it has an i3 or a Xeon, both pretty old. And its maximum PSU is 450W.
Best I would say is that you throw in a GPU, maybe a 1050ti at MAX and use it for what it is. However, if it is a Xeon and 8 gigs or more RAM, buy a 1060, upgrade the PSU and you should be good to go.
