DISCLAIMER - Just a note before hand, all items in this build were purchased during Black Friday of 2017, and thus the prices are set for when I personally purchased them, and then added the tax and shipping costs of everything for that item. I didn't include mail in rebates, as I am only showing what everything cost at the time of purchase.
CPU - I decided to rock the Ryzen 5 1600 for this build, as it has ample power for any of my gaming needs, and should be able to handle any new AAA titles at good settings, making this a powerful mid-range processor. With 6 cores able to be ran at over 3Ghz, I think this is a good solution for most mid range computers.
Motherboard - I'm using the Asus STRIX B350-F ATX motherboard, as this is a full sized motherboard, with plenty of room for expansion, including 4 slots for RAM, and it (at the time) had the best reviews on third party websites, such as amazon and newegg. AM4 motherboards are going to be the norm for any new processors up until 2020, according to AMD. This should future proof for a while.
Memory - At the time of purchase, this was a decent price for DDR4 high frequency RAM, so I ended up getting an alright deal on this dual channel kit. I've heard that higher frequency ram scales well with Ryzen cpu's, so I chose to go with only 8gb of 3000Mhz memory, as I was going for a build that would total under $1000, which I will upgrade with more memory at a later point in time.
Storage - Samsung 250Gb SSD was chosen as SSD's are the new standard for fast gaming, and I can always add on a 2-3Tb mechanical drive for other games. I will end up adding a 500Gb SSD later, when I have the funds, and it should be enough storage for most games and for booting my OS.
Video Card - Okay, the biggest thing that might turn some people off for this build is the GPU that I chose to use. I picked the 3Gb variant of the GTX-1060, which might seem like it doesn't have enough VRAM for modern gaming at ultra settings, but I found that there wasn't much of a difference between the 6Gb version and the 3Gb version. After looking at many benchmarks of other users, I found that for rigs similar to mine, there was only a 10% difference in benchmarks for gaming, and the RAM that I chose can give a 10% boost in performance in games if I make the frequency higher.
Case - I splurged a bit and bought the NZXT as I found it very aesthetically pleasing, and it was made of 90% steel, and it has a nice window to look at the innards of the build. It can support my ATX motherboard, and has lots of clearance room for expansion, as well as a PSU shroud.
Power Supply - I wanted a good PSU that would last for a long time, while being energy efficient, and easy to work with. I got a fully modular 650W Gold 80+ Gold certified model, which I really didn't need to get, but I am getting it for future proofing, and it has a 10 year warranty under the manufacturer.
Operating System - Windows 10, because windows has all the games, and I'm familiar with it.
Wireless Network Adapter - I picked this as I am not close to my router, and I don't want an ethernet cable to be run all the way up to my gaming rig, as it would look pretty bad in the house, and I don't want to shove it under floor boards. It is more than capable of using the speeds that I have, as I am only on a really crappy 3mbps download, 1mbps upload speed (thanks "America's #1 best rated Service Provider for X years") thanks to where I live.
