Another used (somewhat) parts build I put together to sell locally. I had the graphics card, case, power supply, SSD and HDD already, as well as all other parts with a price of $0. I purchased the CPU, motherboard, and RAM new this week due to some decent price drops.
The RX 570 was my son's, he got my old GTX 1070 when I got a 2080 this summer so his old card went back into the parts surplus. It's still a great card so long as you're only gaming at 1080p, most games still hit 60FPS on medium or high settings.
The motherboard came with a recent BIOS installed (Feb 2019) so I did not have to use my spare Ryzen 1200 to flash it for the 2600.
With the price falling down to the $120-140 range, the Ryzen 2600 quickly becoming the bang-for-buck CPU to get. I'm really impressed by the value of this CPU, 6 cores / 12 threads is all you need for gaming and the price is outstanding. I wish AMD could do in the GPU market what they have done for CPUs in regard to increased market competition, performance and pricing.
In regards to aesthetics, I am a firm believer that at this budget level there really shouldn't be any RGB or other "bling" as every dollar spent on that is taken away from performance. This build is more of an exercise in price/performance maximization. That's why I went with an unassuming "office PC" case and no flash or fancy. I tried to just focus on good quality components and good performance for a value.
This computer performs very well in games @ 1080p, I foresee a selling price of $600 with a monitor, speakers, keyboard and mouse.
