Novice PC enthusiast!
Overall, I am a big fan of Be Quiet! and Gigabyte (AORUS). The Be Quiet 240mm Silent Loop AIO is a bit overkill for the Ryzen 5 1600 but the case (Be Quiet Pure Base 600) doesn't have great air flow. I paid a premium for the Be Quiet 240mm Silent Loop AIO but it was worth the cost shipped from the UK. I think I have enough RGB going on so it was a nice RGB(less) addition.
I want to upgrade the video card from the AORUS 1060 6GB to at least a 1080 specifically the AORUS 8GB 1080 Xtreme. It was a bad time to build a PC and at the moment I was freaking out because the price of video cards started to go up. The 1070s were already sold out or price to high (priced at 1080s already) and there wasn't much left so I bought the AORUS 6GB 1060 from NewEgg for about $284 US Dollars. It was in stock and I was in search of a Gigabyte brand video card. The next day the price jumped to $329 for the same video card.
I got lucky with RAM prices and only paid $144 US Dollars from my local Best Buy on the 16GB 3000mhz Corsair RGB RAM. Opted for the Samsung 960 EVO NVMe 256GB M.2 since it was only $10 more compared to the Samsung 950 EVO 256GB SSD. I do have an external 4TB Western Digital drive so I was able to keep the inside of my case clutter free without having additional SATA cables to run/manage.
I would NOT recommend at least the Gigabyte X370 K5 motherboard if you plan on overclocking your Ryzen CPU. You can not manually set the voltage on this particular X370 board in the BIOS. MSRP is $159.99 US Dollars but after a $20 mail in rebate from NewEgg and a additional $35 from Gigabyte the price paid was $95 US Dollars. Currently I'm using the Ryzen Master to overclock at 3.9ghz and 1.38 volts I definitely didn't win in the lottery with this particular Ryzen 5 1600 CPU.
I also had the misfortune of having to replace my first Ryzen 5 1600 CPU when I tried removing the stock AMD cooler to replace it with the Be Quiet AIO. The stock AMD cooler was basically glued to the CPU and I accidentally ripped it out straight out of the X370 socket bending a few pins on the edge. Replaced the damaged CPU with a new one.
