I mainly play Counter-Strike: Global Offensive, and as of recent, Battlefield 4. I hadn't built a PC in a few years and really liked the Carbide 240 Air.
I originally wanted to build an FX-8350 based system, but I couldn't really find a motherboard that I felt was worth the money. I am glad I went I5-4690, but with the liquid cooled system I suppose I could have purchased the K series. Overall it runs everything very fast and smooth.
Battlefield on HIGH settings sits between 78-100FPS, CS GO maxed out easily ~300. The Air 240 cable management system is amazing, I am glad I chose it.
The Radeon R9 280 3GB Twin Frozr hauls ***, also, I haven't seen it past 71 Celsius. The 4690 paired with the H75 hasn't gone past 41C yet even under full load for hours and hours. Great little system - all my PC nerd friends were jealous of how small and powerful it is.
Just purchased new RAM for it, also noticed I entered the wrong SSD originally. This is a completed build shot. I will try getting some 3DMARK 11 Benchmarks today.
