Actually my first build but what you see here are a few upgraded components, for example, my first case was the NZXT S340 Razer Edition, however I upgraded last year to a Enthoo Evolv ATX from Phanteks since I really loved the look of the case and I wanted something more neutral because I grew tired of the green in the NZXT case. Not a perfect case but I really like the Enthoo Evolv ATX.
I use this PC for gaming, video editing and graphic design, although I'd like to upgrade the processor so I'd be able to edit 4k video smoothly because my current i7 is not really for that kind of task (add a bit of color correction and you get 16 hours to render a 12 minute video, for example).
Also, I love small PCs and I've been thinking about building inside the Inwin A1 case, that's mostly because my desk is kinda small.
I play games like Overwatch, DOOM, GTA V, TES V, Tomb Raider, etc. (mostly Overwatch because I my job is very demanding in time).
