New? Or used? What kind of price?
That's extremely entry-level and, if new, you should be able to an order of magnitude better for the money.
If used, it would have to be super cheap to be "worth it" in 2018.
The FX6300 is a 6 year old CPU at this point - the architecture is 7 years old.
16GB of DDR3 is a pointless inclusion to a "gaming" desktop of that caliber.
The RX550 is an entry level GPU that can still be bought new for near it's MSRP of ~$80.
If you're looking at it from a "value" standpoint (FPS in games vs the money paid), it's only really an attractive proposition in the <$200 range IMO. Even then, it's debatable.
*EDIT* Wait. That product number related to a $600 (Amazon, today) pre-built from iBuyPower...
