I bought the Ryzen 5 1600, MSI B350 Tomahawk, Corsair 200R, a Wifi adapter (not included in this build), and 2x8Gb Corsair Vengeance LPX White (also not included in this build) for 450.00$ used on Offerup. I divided the 450$ between the parts since I'm not using them all in this build.
I had previously bought the EVGA BR 500W PSU and a Corsair H100i V2 for 90$. I was excited to use the H100i V2 in this system, only to find that it did not clear the heatsinks on the motherboard. I sold the H400i for 50$ as this is the last build I plan on doing for a while.
I swapped the Corsair Vengeance LPX with a less expensive Adata XPG Gammix kit I had in a different build. I was able to overclock the Adata kit from 3000Mhz kit to 3200Mhz, so it's not much of a downgrade, and the other system got a really nice visual upgrade.
I got stood up tryingto buy a 500GB Samsung SSD for 20$ and a box of .40 ACP Ammo, so I went to a nearby Fry's. Fry's was not a pleasant experience. No good prices anywhere, and absolutely clueless staff. This Hyundai SSD isn't really impressive, although I could have guessed based off of their vehicle lineup. If the store wasn't two hours away I'd return it as I've gotten far better deals online since.
I got the Asrock RX 570 8GB on Newegg with Resident Evil 2 and Devil May Cry 5 included.
No problems with any of the parts, just had to clean out the dust, and reapply thermal paste to the CPU and GPU to make sure they were good to go.
Overclocked the Ryzen 5 1600 to 3750Mhz at 1.35v.
