TLDR; A great build for casual gaming and photo editing. Although I maybe should've picked a slightly longer case. xD
When my old PC (AMD FX 6300 + R9 270 non-X) started to struggle even with the least demanding games and even with light photo editing, I decided that it was time to build something new from scratch. So I started comparing different parts starting with the CPU. I knew I had a Budget of about 1100€ so this build is what it resulted in.
Even though I know that it is not the most powerful rig, it suits all my needs for photo editing in Lightroom and for some Casual Gaming. Most Games run at 60+ fps (1080p) with Ultra to High setttings.
It was pretty easy to build, although cable management can be a pain in the a** especially when you're using sleeved cable extensions. Because I mostly depend on internal HDDs for mass storage and the Drive cage cannot be moved at all (only completely removed) I was left with 7cm (about 2.8 inches) of space between the cage and the PSU but in the end everything fit.
Overclocking the CPU to 3.9GHz was actually quite easy. I tested it with Ryzen Master and then just entered the values into the UEFI. A short test with Cinebench R15 and Prime95 (temps went up to about 64°C) and it was all set. Even the VRMs handeled it quite well with about 60°C avg. under full Prime95 load for 3 hours.
In the end I am quite happy with how it turned out. And in my opinion it looks just great. :)
Edit October 2019: Because my CPU ran quite hot during summer, I switched to an AIO Cooler. I also added an extra of 500GB SSD Storage just for my Game Library.
