I wanted to build something for less than $800 that could play GTAV and other decently demanding games on Medium/High settings. Overall extremely happy with how it turned out.
CPU: Great CPU for a budget build, doesn't hold my GPU back at all and since I'm not overclocking right now the stock cooler is working great.
MB: Amazing board, looks sick and has all the space for everything I needed and more, great manual for finding all the headers and the linked YouTube videos that were in the manual helped a lot.
RAM: Pretty stock RAM, does what it needs to and does it well.
Storage: I'v always used Seagate drives and I have never had a problem with them, this drive is no exception.
GPU: I am so impressed with this GPU, got it for around $210 and plays everything I throw at it on High/Ultra settings.
Case: Another part that I am so impressed with, for right around $50 you get a great side panel, plenty of space, a great front panel with a cool red led fan.
PSU: Got it for $50 and it works great, I know I could have used a lower power PSU but I decided I wanted room to upgrade in the future. Wish it was modular, but then again I had plenty of space to store extra cables.
OS: Windows 8.1 is great in my opinion, works fine.
Wireless: Cheap adapter, plugged it in, installed drivers and it was up and running. Getting 3/4 bars but 20mbp/s download speed.
Case Fan: Got for $6, led is not as bright as I wish it was, but it works fine.
