Another build at last! I like to use the Maxtrexx 55 in builds like this one, but the case had been backordered for several weeks. I found this SAMA-Line ARGB as an alternative, and the quality seemed comparable to the Matrexx 55. The colour changing fan was a nice bonus. Also, you can't see it in the photo, but the RX 470 looks absolutely stupendous. I really like how Sapphire designed the card.   

The specification and cost breakdown (Prices in USD): 
 CPU: Intel Core i5-2500; $0.00
 RAM: 2 x 4GB of Hynix DDR3 @1333MT/s; $0.00 
 MOBO: Intel DH67BL; $29.62
 Graphics Card: Sapphire RX 470 4GB Nitro+; $75.45
 HDD: 1TB Seagate Barracuda; $12.00
 PSU: Corsair TX 650W; $25.00
 Case: Sama-Line-ARGB; $48.03
 Total cost excluding OS: $190.10

The i5-2500 and Hynix RAM were included in another purchase. The other item was well worth what I paid for it, so I considered these components gratis.  

Here are the benchmarks:
All games were tested in 1080p and the FPS is the mean. 
 CSGO: Maximum Settings;186 FPS
 Minecraft: 8 Chunks; 216 FPS
 Apex Legends: High Settings; 84 FPS
 Rainbow 6 Siege: Ultra Settings; 136 FPS
 Fortnite: Epic Settings w/out Shadows; 107 FPS
 Star Wars Battlefront 2: High Settings; 75 FPS
 Overwatch: Ultra Settings; 112 FPS
 League of Legends: Maximum Settings; 170 FPS  

A gaming computer for under $200! I really liked how this build turned out; hopefully I can find similar deals in the future.
