Question Is my PC worth what I paid for it?

Feb 4, 2020
Greetings to everyone,

I would appreciate some advice, criticism and opinions on the build which I am considering purchasing. I made a post about a week ago about purchasing a second hand gaming PC with used parts and a brozen entry level PSU which was a big mistake, I have now returned that PC and gotten my £680 refund.

I was initially going to build it new but found that it is in the best interest of my financial status that I purchase a good quality used PC:

Specifications are:

Cpu: Ryzen 5 2600 with liquid cooler
Gpu: RX580 8GB Gigabyte gaming oc edition
Motherboard: Asus ROG STRIX B350-F
Ram: 16gb (4x4GB) Crucial ballistix 2666mhz white
Ssd: 120gb 2.5" drive (boot drive)
Hdd: 2tb western digital 7200rpm
Case: kolink observatory lite RGB
USB WIFI dongle included.
Fresh install of windows 10 pro activated
Corsair 550W PSU (not sure of specifics as of yet)

The current build has been quoted to me for around £450 which is equivelant to $582

Is this PC worth the money and does it have any limitations or restrictions?

I want to play games such as Battlefied, Warzone, Just cause 4, PUBG and other modern titles at a respectable 1080p at medium settings, may purchase a 144hz monitor but not sure if that would be overkill or not necessary.

Would appreciate all opinions, advice and constructive feedback!
