My 7-year-old computer was having blue screen issues that I couldn't figure out, so I decided to upgrade and build a new one. I'll be using it mostly for gaming / programming / game dev. I decided to use the same hard drive / keyboard / mouse / monitor / speakers I was using with my old computer and save some money, since they are all still working fine for me.
I'm using the front and bottom case fans as intake and the back case fan as exhaust. I did a little bit of stress testing with Prime95 and FurMark, and it stays cool and quiet. I originally had Cooler Master RGB fans for front and back case fans (as shown in the photos), but they were really loud, so I switched to all be quiet SilentWings 3, with Phanteks Halos to add RGB.
