This is a budget rebuild of my dad's 2015 AMD FX PC, with a Ryzen 2600X.
Went for the B450 motherboard, with built in WiFi. Cheapest available DDR4-3200 16GB kit from G.Skill, and a 970 Evo 250GB SSD for the boot drive.
First time building a Ryzen build, after reading about them for almost 2 years. Planning on building one for myself in the very near future, so this was good experience. Inserting the CPU was just like any other AMD CPU in the past, but this was the first time I had to remove a bracket from the motherboard to install a cooler, so that was interesting. The Wraith Spire is definitely a step up from the stock AMD CPU coolers of old. I wasn't sure if it made a difference which way it was oriented, but since the thermal compound was pre-applied, I decided to follow the diagram in the instructions. This meant the little tab with the AMD logo is very close to the RAM slots, pretty much overhanging one of them. Probably would've been better to orient it the other way.
Integrated I/O shield is awesome. Everything fit perfectly. Had to be careful with the SSD heat shield, as it slipped onto the motherboard after I unscrewed it. Didn't realise it wasn't really connected on the other side. I wasn't sure if I was supposed to remove the label from the SSD, but after looking online, I decided to keep it on.
Despite no RGB, which seems to be the norm now, I have to say the RAM looks pretty awesome. Just had time to have a look around in the BIOS and turned on XMP and it automatically switched to 3200MHz (from the default 2400), as expected.
