I built this PC as my 17th birthday gift, and my goal was to make a PC that could run any modern game from this generation at reasonable graphics.
I was initially nervous about the Pentium G4560 CPU, but it worked much better than I thought it would. The only time it's an issue is during intensive physics benchmarks - from what I can tell it isn't an issue during normal gameplay.
The case is fantastic looking, but I would suggest going for the RGB model instead of the model I have chosen, as it comes with 2 additional fans and I believe looks a lot better.
My only real trouble with this PC is the fact that the RAM is incredibly hard to insert - though once it is in it works like a charm.
This PC can run Overwatch at max graphics at 60 fps, Fallout 4 at max graphics at 60 fps, Fortnite at max graphics at 60 fps and Dishonored 2 at medium graphics at 60 fps (I believe this is due to optimization issues, and is fixable by editing config files - will have to test further).
All in all a fantastic experience for a first build, learned a lot from it and am incredibly happy to have this PC sitting on my desk right now.
