To be honest i have run AMD exclusively on my systems from back in the Amd Duron 900 days.
I would agree with StrangerDanger that AMD was a bit finicky when they couldn't compete with Intel but since the introduction of Ryzen Zen cpus its has changed the pc world completely, although Nvidia has an performance edge on Amds graphics cards(since you dont want to game the gpu i suggested is just for getting a signal to the monitor and video playback)
I have built a few systems for friends and family and so far had no complaints. My current personal system is a Ryzen Threadripper 1950x and a AMD Vega 56 gpu,i am watercooling them both with blocks from watercool.de (best in the business in my experience)
Also i looked at the system i showed you and you can scratch off the cpu cooler for another 35 usd savings(i didnt notice at first that the cpu comes with the cooler bundled)
