Originally I intended to use this for school work. After a couple days of causally playing some steam games I found out it is actually a decent gaming computer. I didn't include any peripherals in the build because I'm not going to try to tell anyone the best mouse/ keyboard, or monitor so you guys can pick those. For the operating system I went with Windows 10 Pro. It is amazing. For monitors I am currently using an extra 32" flat screen I had laying around and an old 17" Acer as a secondary monitor. As for mouse and keyboard I picked up a Windows 200 series keyboard for $5 at Microcenter and a nice Adesso mouse that has three different color options for $15. Now for the problems I have ran into thus far. The Corsair 200r case is a decent budget case, 2 USB 3.0 in front along side a microphone and headphone jack. This case can house up to 7 fans which is a problem due to the fact that the motherboard will only support 3 fans. To counter this problem I picked up two fan splitter cables for only a couple bucks each. I have the two stock case fans, the intake in the front of the case and the exhaust in the rear, I also mounted two 120mm fans on the side to help cool the CPU and GPU and it stays cool even in my living room which is usually around 70 degrees f. Now for the gaming specs. I haven't played many games but the games I have played have amazed me. COD Advanced Warfare on High Settings: constant 30 FPS Dirt Rally on high settings: 45-50 FPS Counter Strike GO on high settings: 60 FPS Left for Dead 2 on high: 45-50 FPS. If you have any questions feel free to comment! Here within the next couple weeks I plan to upgrade my GPU so any suggestions would be appreciated!
