For 4k games and Films. I forgot I owned the Inwin A1 with the ****** power supply and decided to make a build with it. I went with the corsair ecosystem because I needed to change the unreliable power supply and also the LED strip on the bottom base since the motherboard doesn't have a 12v RGB header. At first I decided to go with a i5-8400 but it was bottle necking the RTX 2080 super and rather than downgrade the GPU, I decided to upgrade the CPU to a 9600k. Only hiccup when building the system is that I didn't noticed the motherboard only supports RAM speeds up to 2666 and I went and bought 3200 speed (not planning to change as i'm too lazy).
